4 2017 Team Guidelines & Procedures 1) MECA teams are created by the Retail Members and Manufacturer Members to enhance their customers and employees visibility at MECA events. MECA team members can travel together, work together, and enjoy their MECA experiences more when part of a properly managed MECA team. The team is recognized when the Retail Member or Manufacturer Member pay the yearly membership fee. 2) MECA teams can be independent, and the team must pay a yearly membership fee of $50 for this official recognition and service. 3) MECA team members must tell the event registration person that they are on a team, and make sure that this is entered on their score sheet on the line that says MECA Team. The MECA member MUST present their membership card and make sure that their membership number is listed on the score sheet. They must do this at every event with every score sheet. 4) MECA team members must be MECA members in good standing to be listed as team members in the event results. This means that their membership must be current. 5) MECA members who are on MECA teams will have that team name listed next to their event results on the web site. This takes extra time and effort, and is much easier to process when the score sheet is properly filled out, listing the MECA team on the appropriate line. 6) MECA team registration includes one competition membership, good for one competition vehicle. A membership card will be issued to the Retail Member, Manufacturer Member, or independent team for the vehicle. This vehicle is usually for the owner of the store or manufacturer representative s demo vehicle, but it can be assigned to one competitor, and only one competitor, for the season. For independent teams, the card is usually for the President or competition leader, but it can be issued to a designated team member for competition registration and privileges. 7) We have established a MECA Team Participation Award that is presented at the end of the season. It is presented to the team that has the most members entered at MECA shows throughout the season. Each member counts one time, for each event attended. This is not based on the number of entries each member makes at the show, but on the fact that they were there and competed. For example, Jimmy Loud of Team Really Loud get 1 point for being at the show, not a point for each format entered. If 5 team members enter a given event, then the team gets 5 points toward the Team Participation Award. 8) If a MECA team member is not properly recognized in the Event Results, then the team captain or team member can notify the Event Director, or Commissioner if necessary, of the mistake, or omission, and have it corrected. MECA strives to accurately report all event results and facts at all times.

6 I. Purpose & Intent MECA is the sanctioning body for competitors involved with car audio sports. MECA is a membership association formed to encourage, support, and reward competitors involved in car audio sports. This Rule Book is intended to outline the specifics of competition in the Sound Quality League (SQL). It is the responsibility of each competitor to review, comply, and honor the rules in cooperation with event officials. MECA strives to present every competitor with a fair and unbiased forum in which competition is regarded as worthwhile and enjoyable. Intentional cheating and/or manipulation of the rules will result in permanent suspension from MECA competitions and events. Alcohol, drugs, weapons, and violence of any nature are prohibited at all MECA events. II. Objective The Sound Quality League (SQL) working with the established criteria in the MECA Rule Book, will objectively evaluate each competitor s vehicle and system. Appropriate and individual attention is given to Sound Quality (SQ), Installation (Install), and Real Time Analysis (RTA Freq Out). MECA s SQL philosophy reflects the importance and regard for the best sound quality presented to the judges. Seven (7) SQ classes will be offered at Double Point (2X) events with the full SQL Event Menu (Seven (7) SQ, Four (4) Install, and One (1) RTA Freq Out class) being offered at larger, 2X events, Triple Point (3X) Soundfests, and World Finals. SQ2 (2 seat judging) will be offered at the host s discretion. The vehicles with the best sound quality will win the SQ awards. The vehicles with the best installation qualities, especially regarding safety and appearance, will win the Install awards. The vehicles with the best RTA scores will win the RTA Freq Out awards. The vehicles with the best scores, indicating the best sound quality judged from 2 seats, will win the SQ2 contests. III.

18 All consumer, sponsored, and professional competitors are allowed to compete in the Extreme class based on the guidelines below. The Extreme class will showcase the most radical of vehicles with the sole purpose of gaining every advantage possible for sound quality in a mobile environment. Class Requirements Vehicle will be judged from the Driver s Seat with the engine off. MECA approved audio tracks will be used for judging. CDs or competitor provided USB flash drives or IPods are allowed. Finals will be judged using judging materials of the highest possible quality. All car audio equipment (including amps, speakers, subs, enclosures, etc.) must be safely and securely mounted. Vehicle must run and be drivable from the driver s seat. Manufacturer vehicles are not allowed Components No restrictions Speakers No restrictions Electrical Upgraded electrical and charging systems Batteries must be securely mounted (and covered if in a truck bed) Interior Modifications No restrictions Safety No restrictions Cosmetics No restrictions 16

19 event status). Anyone who works for a 12-Volt manufacturer in any way must compete in this class. Any vehicle that is regarded as a factory demo vehicle or owned by a manufacturer belongs in this class. Anyone who believes that they have the experience and ability to compete in the Master class may do so. This is an expert class which gives competitors and vehicles with an unfair advantage over other competitors the opportunity to be part of MECA. Trophies may or may not be awarded (depends on the sponsor or Class Requirements Vehicle will be judged from the Driver s Seat with the engine off.

20 V. Best of the Best of Show (BOBOS) Award The winner of this award will be the Competitor with the best overall audio system performance at an event based on their competition results, determined by the following scoring system: BOBOS Competitors must enter SP (non-x class) and SQ to qualify for the award. Park & Pound, Install, and RTA Freq Out points will be added to get the overall BOBOS score. Using the Competitor s score in SP measured at the headrest, Park & Pound, SQ, RTA (score x 2), and Install, those scores will be totaled to get an overall score, with the highest overall score winning BOBOS. SP offers a maximum score of 150 db, Park & Pound offers a maximum score of 130 db, SQ is a maximum of 100 points, RTA Freq Out is a maximum of 80 points (perfect score of 40 x 2), and Install has a maximum of 100 points. For example, if a Competitor has a db in SP at the headrest, db in Park & Pound, a 78 in SQ, a 32 in RTA, and 81 in Install, then it would be calculated as: SP is capped at 150 db and the RTA Freq out score is doubled. So, = 499. Tie-breakers: 1st SQ Score; 2nd SP Score; 3rd Install Score; 4th Park & Pound Score; 5th RTA Freq Out Score. Even if they are offered, SQ2, Show & Shine, Ride the Light, Boom & Zoom, or Dueling Demos are not factored into the BOBOS scoring. Phat awards and Best of Show awards are not factored into the BOBOS scoring. VI. SQL Best of Show ( The Zenner ) Award The winner of this award will be the Competitor with the best overall audio system performance at an event based on their competition results, determined by the following scoring system: SQL BOS Competitors must enter three SQL formats to qualify for the award: SQ, Install, and RTA Freq Out. Using the Competitor s true individual scores in SQ, Install, and RTA, those scores will be totaled to get an overall score, with the highest overall score winning SQL Best of Show ( The Zenner ). Tie-breakers: 1st SQ Score; 2nd Install Score; 3rd RTA Freq Out Score. Even if they are offered, SQ2, Show & Shine, Ride the Light, or Dueling demos are not factored into the SQL BOS scoring. Phat awards and SQ Best of Show awards are not factored into the SQL BOS scoring. VII. Judge A competitor may earn no more than 20 Judge during the season. These are last place points taken when a competitor is part of a Judge Team at an event and approved by the Commissioner as necessary. The results are listed with a score of zero 0. Judge count toward qualifying for State and National Titles as well as World Finals invitation just as points earned from competition. VIII. General Rules A. Vehicle/Owner Requirements 1. No part of the vehicle or the installation will compromise the Judge, passenger, or spectator safety in any way. 2. Vehicle and audio system subject to inspection by Judges at any time. 3. Vehicle and install must pass safety inspection. Safety inspection will consist of checking wires and connections under the hood and solid mounting of amps and amp fuses. 4. Any member vehicle that is determined to be unsafe may compete at the first event and receive points, but must have safety issues resolved at the next event. Failure to resolve safety issues after the first event may prohibit participation at future events. 5. Any safety issues or judging calls made during an event will be recorded on a log sheet. This sheet will be passed to the MECA R&E Committee to give final approval of any issues that arise which may not be clearly identified in the rules. 6. Competitor and Team must accord all Judges proper respect and courtesy. Any unsportsmanlike conduct may result in disqualification and/or suspension. B. Judging Criteria 1. The Judge will sit in the driver s seat and will be the only person allowed in the vehicle during scoring. 18

21 2. All judging will be performed with the engine off, including when checking for system noise. a. Noise is to be judged with music and zero bit tracks, at varying volume levels, and from normal listening position. When noise is audible and interferes with listening experience, points are deducted (see chart page 17, VIII, B). b. Only system related noise should be evaluated, and when necessary, deducted accordingly; for example, alternator whine, on/off pop, is no longer deducted. also should not be deducted for fans running, relays turning on/off, CD spinning inside the head unit UNLESS they can be heard coming through the speakers. 3. Driver s seat may be positioned however the Competitor wishes. Seat rails may only be relocated in Modex, Extreme, and Master classes. All other classes may not modify the factory position of the seats. 4. Judges will use approved tracks for listening, listed here and Addendums 2 and 3: a. The Chesky Ultimate Demonstration Disc b. MECA SQL CD Positive Listening Volume 2 and/or Tantric Tuning c. MECA Bonus Tracks commercially available (e.g. Keb Mo s Suitcase, Janice Ian s Breaking Silence, etc.) 5. The Chesky Ultimate Demonstration Disc evaluation tracks are listed with each sound quality criteria section in this Rule Book. 6. Judge s listening level will vary ( db) during judging to assess all system criteria. 7. Score breakdowns are to be used as a guide. In order to place in a certain point category, a system does not have to represent all criteria defined; it is used as a majority ruling. Common sense and objectivity should be used when viewing the score definitions. 8. Sound Quality class assignments are based on the complexity of the system and installation. 9. When a system failure occurs, the Competitor will be given 5 minutes to make adjustments and present system to the Judge. 10. The Sound Quality SQ Best of Show award will be presented to the Competitor who receives the highest SQ score in the Sound Quality contest. The Install Best of Show award will be presented to the Competitor with the highest Install score. The Sound Quality League SQL Best of Show award will be presented to the Competitor who received the highest total score among all SQL formats (SQ, Install, and RTA Freq Out). 11. MECA Members must compete at their State or Regional Finals for State Championship in that class. If no State or Regional Finals is offered, the highest qualifying score in each class will earn the State Championship. 12. MECA Members must obtain a minimum of 40 points to qualify for the World Finals Soundfest. The Member must compete in at least 2 events with the vehicle intended for World Finals Soundfest competition. 13. will be awarded for the purpose of determining National Champions. The points will be as follows: For single (1X) points contests: 1st = 5 points, 2nd = 4 points, 3rd = 3 points, 4th = 2 points, 5th = 1 point. There will be double (2X) points contests and Soundfests will be triple (3X) points. The Competitor with the most points in each class is the National Champion for that class. 14. Any disputes or protests are to be respectfully presented to the Head Judge prior to the start of judging so that the Competitor being protested has time to correct any problems and comply with the rules. Protests may only be filed by another Competitor in the same class as the vehicle/system protested. 15. Any rule interpretations made during an event will be recorded on a log sheet. This sheet as well as an will be passed to the MECA R&E Committee to give final approval of any issues that arise which may not be clearly identified in the rules. The MECA R&E Committee will have 5 days to make a final decision regarding any rule interpretations; decisions made will be final for the remainder of the season. 16. Judges decisions are final. If a Competitor has questions concerning misplacement in class or any other irregularity, the Competitor may contact the MECA R&E Committee for review. C. System Requirements 1. Use of equipment that has been converted to 12-volt power is allowed only in Modex, Extreme, and Master classes. 2. Power, volume, and track functions must be accessible and viewable from the Judge s listening position. 3. No modifications or additions to audio or electrical systems after verification. Replacement of same make and model equipment is allowed. D. Sound Quality Contests and Classes 1. Sound Quality classes offered are determined by the Commissioner and the host, promoter, and/or sponsor. Sound Quality classes will be listed prior to the event on the event flyer and the web site schedule. 2. For single point (1X) SQL Events: Stock, Street, Modified Street, and Modified classes will be offered. Modex, Extreme and Master classes are optional. 3. For Double Point (2X) and all Soundfest Triple Point (3X) SQL events, all SQ classes will be offered: Stock, Street, Modified, Modified Street, Modex, Extreme, and Master. 4. The separations of the Sound Quality League classes are intended to show progression in the complexity of system design, with an overall focus on the sound capabilities of the vehicle. The parameters set in the classes allowed/not allowed lists are designed to focus on vehicle modifications, and whether those modifications are going to benefit the sound signature. 19

22 Also, the allowed/not allowed parameters are intended to focus on whether the vehicle has an unfair advantage that is beyond the intent of that class. If an unlisted or unspecified modification in the vehicle does not enhance or benefit the vehicle s sound signature, then it does not fall within our rules and should be allowed. If a grey area item/modification is identified during vehicle classification, the item/modification should be submitted to Rules and Ethics for a decision in a timely manner to avoid future issues. 5. It is preferred that all 3X points contests use 3 judges to score and rate the Sound Quality of the audio systems. When/where judges are not readily available, 2 judges may be used, and 1 judge as a last resort but highly discouraged. With multiple judges, the score sheets are averaged to determine the winners in each class. Score sheets should be turned in to the scorekeeper with no discussion among the judges or the scorekeeper. Score sheets should be complete when turned in to the scorekeeper (does not have to be totaled, but needs to have every category filled out). Judges' scores are to be independent and based only on their experience listening to and rating approved contest tracks. State, Regional, and World Finals contests must use the 3 judges method for determining winners in each class. For any Finals and big contests, 2 sets of three judges may be used. First set will judge Stock, Street, and Modified Street class. Second set of judges will evaluate Modified, Modex, Extreme, and Master classes. When there is a tie, these tie-breakers are to be used: a. Sum of Tonality scores b. Sum of Realism/Believability scores c. Sum of Ambience scores d. Sum of Dynamics/Impact scores e. Sum of High Level Linearity scores 6. The Competitor must make sure that their correct class is listed on their score sheet, so that points can be tracked accordingly. 7. SQ2 has 2 classes, with sound quality score sheets for driver and passenger seats judged simultaneously. Both score sheets are added together. Highest score wins. MECA Members must compete in two (2) SQ2 contests to qualify for State Championships and SQ2 entry at Finals. SQ2 class includes all systems that qualify for Stock, Street, and Modified Street SQ classes. SQ2+ class includes all systems that qualify for Modifed, Modex, Extreme, and Master SQ classes. IX. Score Sheet Guidelines A. Safety Inspection (Pass or Fail) The verification Judge will perform the safety inspection. The following may disqualify a vehicle: 1. Improper electrical overload protection, terminations, cabling, or routing of any part of the system that could cause harm to the Judge, Competitor, passengers, or spectators. 2. Improper mounting of any piece of the system that could cause harm to the Judge, Competitor, passengers, or spectators. 3. Any portion of the install that does not meet with the class verification rules. B. System Noise (Maximum points deducted: -2) Deductions 0 No Noise 0.25 Audible at low volume levels, db 0.50 Audible at moderate volume levels, db 0.75 Audible at most volume levels 1 Audible at all volume levels There will be a deduction from the total score for each instance of the following heard through the speakers: 1.

D. Musical Realism 1. Dynamics/Impact (Maximum points awarded: 5) Competition disc examples: Tracks 3, 17, 19, 25, 29 The reproduction of dynamics is the element of musical expression relating to the degree of loudness or softness of a sound. The dynamic range pertains to the useable range of extremes between loud and soft portions of the reproduction. These differences should be smooth, transient, and accurate. No distortion will occur at either loud or soft portions of the reproduction. Realism of Dynamics 21

24 1 Soft portions lack detail or are not at all apparent; attack is weak; decay is extremely inaccurate; distortion occurs at low to moderate (80-95 db) levels.

Ambience (Maximum points awarded: 5) Competition disc examples: Tracks 3, 11 Ambience is part of the listening environment that is not a direct result of the musical source. The music should appear to originate in front of the listener, yet there should be a sense of space around the listener. The room size, treatment, and room noise all combine as part of the illusion of being in the audience or in the same room where and how the music was originally recorded. The ideal perception will have full detail with no distortion or confusion. Realism of Ambience 1 Reproduction of room size is inaccurate and/or ambience is either completely lacking, or overtly manipulated. 2 Room size is somewhat defined but inaccurately reproduced. 3 Room size is defined but inaccurately reproduced. 4 Room size is very defined but somewhat inaccurately reproduced. 5 Room size is extremely defined and reproduced in an extremely accurate manner. 5.

Cabling & Power Flow (Maximum : 10) a) All components are mounted securely and attention has been given ensuring that system design is safe. These include: batteries, fuse holders, circuit breakers, capacitors, alternators, and over power overload and protection equipment. All wires and connections are appropriate size and secure, routed correctly, and protected throughout the system and vehicle. b) Fusing or manual reset circuit breaker(s) must be located within 18 of battery termination. c) Use of an Install Book with pictures is encouraged to demonstrate proper attention to safety practices. Considerations are: proper use of grommets, additional sheathing or loom of the cable in high stress areas, no compromise in the performance of the cabling, and overall integrity of cabling installation. Cabling & Power Flow 0 No thought or consideration to vehicle safety, not only in choice of appropriate conductor size, but in aspect on installation of cabling. Wire passes directly through metal with no barrier, i.e.: grommet, factory boot, etc. (Wire techflexed or loomed through a hole and silicone into place would pass, but be awarded minimal points.). System is extremely unsafe. 1 3 Minimal efforts given to conductor size, use of grommet or factory boot, wire techflexed or loomed through hole and secured into place. Wires can be seen, exposed wire in connectors, wires spliced together, no protective covering in place Vehicle is unsafe. 4 6 As above, with some effort to provide adequate protection and safety of all wires, cable clusters, connectors, and power-flow components. 7 8 Extensive efforts used to ensure wire safety, protective covering in place, consideration given to appropriate wire size, all wires are hidden (unless point of install is to show how wires are run). Wire ran through a protective boot, or grommet of appropriate size Over the top considerations in safety and convenience. Wire is appropriate size or in excess, all wires are covered by protective material, each wire separately identified, cabling secured to the vehicle every 8 inches or less.

To score 15 points, the Competitor must have documentation of all equipment, including specifications of all speakers, amplifiers, source units, equalizers, signal processors, batteries, etc. When there is a tie, this tie-breaker is to be used: Sum of Execution scores breaks the tie XI. RTA Freq Out Format Rules Intended for Sound Quality League Competitors to rank Real Time Analysis scores. A. Vehicle/Owner Requirements 1. Vehicle must be street legal (registered and licensed, with seat belts, automotive seats, glass in vehicle, brakes, lights, etc). 2. Audio system must qualify for Sound Quality League formats. 3. Only the owner/member or Support Team member may sit in the passenger seat during the test. 4. Test may be performed with Competitor outside of the vehicle. B. General Judging Criteria 1. Any RTA meter may be used for Single (1X) and Double (2X) Point Events. The TermLab Magnum is the official MECA RTA Freq Out meter for all Triple (3X) point Soundfest events and MECA World Finals. The MECA mode on TermLab s Event Promoter Pro (with a 40 point scale) in the RTA analysis program will be used at 3X Events and World Finals to determine score. 2. Doors and windows are to be closed, Engine must be off. 3. Recommended test source is Mono Pink Noise from MECA SQL CD, or MECA SPL Test CD track #14. Same CD and track must be used by all Competitors in the contest. 4. Competitor, with Judge s help, sets reference level at 90 db using the number scale. 5. Competitor is given 2 minutes to make adjustments. Adjustments can only be made one time. If there is a tie, the tiebreakers are made with no additional adjustments, other than the main volume control. 6. Testing interval is determined by the scoring program, but not to be more than 30 seconds. 7. Judge takes 3 tests per round and the Competitor keeps the highest score in that round. 8. Scores are ranked from highest to lowest. Highest score wins. 9. Ties for 1st, 2nd, and/or 3rd place will be settled by a re-test. For the first re-test, volume is increased to 96 db. Each round of re-tests, thereafter, will be performed at increases of 3 db i.e. 1st tiebreaker would be at 96 db, 2 nd tiebreaker (if necessary) would be at 99 db, 3rd would be at 102 db, etc. Highest score wins tiebreaker. Scores in tie breakers do not effect scores set in 1st passes and cannot be used to earn a place higher than the tie for which the tie breaker was done. C. Additional Judging Criteria for 3X Events and World Finals (TermLab Magnum) 1. Using the SPL portion of the TermLab Magnum, the competitor, with Judge s help, sets reference level at 90 db. 2. The Competitor is then given 2 minutes to make adjustments with the TermLab Magnum set at Slow speed. 3. Still set at Slow speed, the Judge takes 3 tests by freezing the read-out on the screen. Competitor keeps the highest score. 4. For the 1st Round Tiebreaker the speed is changed from Slow to Medium, volume is increased to 96 db, and all other settings remain the same 5. If a 2nd and/or 3rd round tie breaker is necessary (99 and 102 db), with all other settings remaining the same from the 1st Round Tiebreaker. 6. If a 4th and/or 5th round tie breaker is necessary (105 and 108 db), with all other settings remaining the same from the 3rd Round Tiebreaker. D. Microphone/sensor Placement 1.

The Mic/Sensor Stand will be placed in the Driver s seat with the stand slid to the rear of the seat as close to the seat back as possible and sitting flush against the seat bottom. 28

31 Some unique situations may arise that can disqualify a vehicle or system from RTA Freq Out. These are determined by MECA judges. XII. SQL Phat Award Rules Sound Quality League Phat Awards are intended to recognize special vehicles and systems in the contest. They are picked by the judge team and the following criteria are used: 1. SQL Phat Car - The best car involved in SQL contests at the event. Judges look for best paint, aftermarket accessories including wheels and tires, audio system integrated into the vehicle, audio system performance, and overall cleanliness and appearance. This would be the car that most people would choose from all the others, if they were able to own it themselves. 2. SQL Phat Truck - The best truck involved in SQL contests at the event. This would include all SUV s, vans, pickups, Jeeps, Hummers, and minivans. Judges look for best paint, aftermarket accessories including wheels and tires, audio system integrated into the vehicle, audio system performance, and overall cleanliness and appearance. This would be the truck that most people would choose from all the others, if they were able to own it themselves. 3. SQL Phat Install - The best audio system installation in a vehicle involved in SQL contests at the event. Judges look for integration into the vehicle, cosmetic appearance, degree of difficulty, and performance of the system as criteria for selection. This would be the flashiest, most remarkable installation at the event. 4. SQL Most Improved - The Competitor that has raised their Sound Quality score the most since their last MECA contest is the SQL Most Improved. 5. MECA Phat ICE Award (All vehicles are eligible for this award) - The best in-car entertainment system involved in any contests at the event. This includes monitor screen(s), audio system, game system(s), and all equipment relating to a sophisticated entertainment experience. Judges look for integration into the vehicle, cosmetic appearance, degree of difficulty, and performance of the system as criteria for selection. This would be the flashiest, most remarkable entertainment system at the event. XIII. Glossary of Terms Audibility (of flaws) From best to worst: Inaudible, subtle, slight, moderate, significant, conspicuous, severe, extreme, and intolerable Accuracy This is a very positive term, generally referred to as Fidelity to the recorded sound. It may sound like a recording (bad microphone, poor engineering etc.). Aggressive Negative term for sound that is excessively assertive, bold, and energetic. Analytical This is a negative term where the detail of the music is over emphasized, similar to turning up the sharpness on a television. Articulation/ Muddy: The reproduction of inner detail in complex sounds, which makes it easy to follow an individual sound among any complex sounds. Poor articulation would be congested: smeared, confused, muddy, and unexciting. Attack Refers to the initial of sound an instrument makes (usually percussive but not always), which is followed by decay. This is a large part of pace and rhythm and is describing transient speed. Boomy Excessive accentuation on the midbass akin to singing into a barrel (New York Times). One-note bass is another example. Closed-in The spatial characteristics of a musical event are lost due to a HF roll off. Coloration A tonal sameness to reproduced sound. Every track has the same deviation from tonal neutrality. Cupped-hands 29

32 Coloration similar to speaking through cupped hands. Damping Similar to the Damping factor in amplifier specifications, under-damping causes loose, heavy bass; over-damping yields very tight but lean bass either covers a broad frequency range. Detail Refers to the amount of low-level resolution a system is capable of during solo or soft passages, similar to articulation. Poor detail would be Haze/ Fog. Effortless During loud passages the system shows no signs of audible stress. A positive term that implies power, headroom, proper system design and proper enclosure volumes. Euphonic Deviation from tonal neutrality that is pleasing to the ear. Focus The audible version of the optic term, or the distinctness or clarity of an image. Forward/ foreshortening The instruments appear closer than they should and can affect the illusion of depth. Harsh A negative term. Unpleasant, disagreeable, unnatural, or causes discomfort. Hooty Resonant colorations may cause some lower-midrange notes (human voice) to jump forward or hoot at the listener. Hot Very tipped-up frequency range, USUALLY high frequencies. Imaging A term for the ability to pinpoint the actual sizes and locations of the instruments and location of the vocals. Lean Slightly bass-shy. This is the effect of a bass roll off below around 500 Hz. Musical, musicality A term for a pleasant sound that resembles live music, not necessarily accurate or realistic. Nasal Pinch your nose shut and talk... that s the sound. Sound that comes from the nose. Palpable Describes reproduction that is so realistic you feel you could reach out and touch the instruments or singers. Realism The nature of an audio system to reproduce an actual musical event in a vehicle. Similar to accurate but this is a judgment on how the system compares to the original event not the recorded event. The combination of realism with accuracy is the ultimate goal of sound reproduction. This will not sound like a recording. Sibilance A coloration that resembles or exaggerates the vocal s or sh sound, like a hissing sound. Stable Imaging Very desirable. A lack of movement of an instrument as it plays different notes. Strained Sounds like the system is on the verge of overload (i.e. cone breakup, possible clipping). 30

33 Suck-out A deep, usually narrow frequency-response dip. Timbre The combination of qualities of a sound that distinguishes it from other sounds of the same pitch and volume (a piano, clarinet, oboe, and violin can hit the same note but not the same timbre). Tubby Mid-bass and upper bass notes that sound accentuated, somewhat boomy, out of proportion and not natural or precise. Visceral Viscera is The soft internal organs of the body, especially those contained within the abdominal and thoracic cavities so visceral impact is a gut shot. A sensation of the body relating to pressure or concussion from bass dynamics. 31

34 5 Dueling Demos Classes Street+, Modified, Extreme for cars and trucks. Motorcycle. MECA Kids (vehicle registration and license rules not applicable) Sound Quality League Dueling Demos contest is intended to recognize the strongest music systems with regard to power, clarity, tonal balance, and intensity.

(5) Vehicles must park with front bumpers or rear bumpers (if possible) about 1 from each other, in front of judge table. Some locations cannot house this set up, so, modifications are permitted depending on location. (6) Once parked, the Competitor has 1 minute to get out of the vehicle and prepare for the demo. (7) The Competitor may reach into the vehicle to turn system on and off, as long as they are wearing hearing protection, and their head remains outside the vehicle. (8) Maximum engine idle is 2000 RPM s. (9) Competitor must win class, or be selected best in state and have 20 points at the conclusion of the State/Regional Finals Soundfest, to be declared State Champion. 40 points are required in the class for World Finals Soundfest eligibility. (B) Owner Requirements All Classes (1) Competitors and/or someone in their family, must own the vehicle that is used in competition. Driver s license and vehicle registration required to verify eligibility for State Championship, and/or World Finals Soundfest eligibility. Regardless of registration, a vehicle may not be used by more than one Competitor at a show. Additionally, a Competitor may not use another Competitor s vehicle. (C) Judging Criteria All Classes (1) Winners are determined by people s choice or Judge Panel. Crowd directed to stand by their choice after demo. The demo with the most support wins. Crowd response, i.e. applause, screaming, yelling, dancing, etc. may also be solicited. When possible, a panel of 2 to 3 judges is chosen in place of the people s choice format. With a Judge Panel judges are required to get a 360 degree listening experience of the vehicle and not focus on just one aspect (aka, the sweet spot). (2) Competitors challenge each other, and when necessary, a bracketing system will be used. 32

35 (3) Contest winner determined by success in qualifying round(s), and final round(s). (4) Coin toss, drawing straws, number guessing game or other fair method determines demo order. Winner may go first, or choose to go second. (5) Each Competitor has 1 minute to play their demo. Demo may be 1 song, or multiple songs. (6) Competitors must use commercially available tracks, and may choose their song and source material. Any source is permitted. (7) Song must be played full range, with highs and mids that are audible. Songs may be bass songs, and do not have to have lyrics but, if they have lyrics, they must not have any foul or offensive language. (8) Any combination of open doors, windows, trunk is permitted.

Said tweeters can be no larger than 3 inches in diameter including the mounting. Horns are not considered tweeters. Only exception will be vehicles with rear deck locations. These speaker locations most likely already pass the window line from the factory. Competitors who choose to mount speakers inside the trunk, said speakers must remain within the confines of the trunk and cannot protrude from the trunk (i.e. mounting speakers to the trunk lid). For hatchback competitors, some vehicles come equipped with speakers in the hatch door. Said competitors are allowed to use this location in street, but are limited to standard size speakers for said location. Truck beds, while considered to be cargo area, are also external so any competitors choosing to mount speakers inside the bed of a truck do not qualify for Street class. (3) All speakers must be mounted to the vehicle in some form or fashion and must remain within the confines of the ICA or passenger compartment area of the vehicle. No externally mounted speakers will be allowed. (4) Door panels may be modified with the purpose to add additional speakers, but the factory door panels must be the basis for these additions. To clarify, one cannot remove the factory door panel and simply replace it with a piece of wood. (5) Street competitors are limited to 12 speakers total (subwoofers are excluded). 2-way (Co-axial), 3-way (Tri-axial), 4-way and 5-way speakers are considered 1 speaker. Modified (1) All audio equipment must be mounted in or on the vehicle (aka, no external power supplements or freestanding equipment). However, head unit may be held outside the vehicle or used in a podium. (2) All speakers must be mounted to the vehicle in some form or fashion. Externally mounted 33

36 speakers are allowed as long as there are mounted in the confines of the original shell of the vehicle. For example, roof mounted speakers are not allowed, but mounting speakers underneath the vehicle is acceptable. Externally mounted speakers cannot change the physical shape of the vehicle in any manner. Speakers mounted in the bed of a truck are acceptable as long as all aspects of the speakers and anything attached to the speakers (i.e. mounting spots, enclosure) are secure and safe. If any portion of said equipment does protrude from the truck bed, the vehicle will be placed in Extreme. Trucks with camper shells will be treated as an SUV as far as limitations on speaker locations. (3) There are no limits to speaker locations inside the confines of the vehicle. (4) Modified competitors are limited to 28 speakers total (subwoofers are excluded). 2-way (Coaxial), 3-way (Tri-axial), 4-way and 5-way speakers are considered 1 speaker.

Judging Criteria All vehicles are judged on cleanliness and attention to detail. Modifications are only taken into account in classifications and scoring for Integration of Aftermarket Equipment and Consistency. If modifications have not been made, score using the vehicle s Accuracy of Showroom Condition instead of Integration of Aftermarket Equipment. III. Score Sheet Definitions A. Interior All aspects are judged on cleanliness and attention to detail. No modifications are to be taken into account on this part of the score sheet. B. Exterior All aspects are judged on cleanliness and attention to detail. No modifications are to be taken into account on this part of the score sheet. C. Engine / Trunk All aspects are judged on cleanliness and attention to detail. No modifications are to be taken into account on this part of the score sheet. D. Overall Vehicle Appearance This category critiques the overall appearance of the vehicle in 2 categories. Consistency of the Vehicle deals with the overall modifications of the vehicle as it contributes to a theme of the work. Theme can be easily defined as What look was the owner going for? Was the owner going to a low rider, import tuner, muscle car, and something different? This can also be defined as Do the modifications flow with the vehicle s appearance? When you look at the vehicle, does everything have its place and does it belong there? Creativity deals with the owner s ability to make unique aspects of the vehicle stand out amongst others. E. Integration of Aftermarket Equipment Modifications are scored in this category. Vehicles are given points for not only modifications, but also, how the modifications are installed. For example: - Is the speaker enclosure flushed into the trunk and covered in fabric to match the vehicle or is it a simple prefab box? - Is the aftermarket ground effects kit painted to match the car or is it primer and attached with sheet metal screws? Are the aftermarket seats professionally installed with modified seat rails or factory seat rails? OR Accuracy of Showroom Condition For vehicles with no modifications and dedicated to the appearance of a new vehicle on the showroom floor. Missing or incorrect pieces, discoloration or stains, imperfections of any kind are scored. A brand new vehicle on the showroom floor would score a perfect 5 in each category. 37

41 MECA s main goals are FAIR & FUN events for Competitors involved on the event day. These guidelines are intended to ensure that our Competitors are treated ethically and respectfully. When the events are fair the Competitors can have more fun, knowing that the Judge Team is following the Rule Book and treating everyone the same, in accordance with the Rules. Judges are at the event to evaluate and help the Competitors and to make sure that safety issues are handled properly. A copy of the rule book should be at every MECA event. I. Judge Definitions Meter Operator - Training on operating the computer or meter is required. Anyone may do it, supervised by the Head Judge. Sensor/Mic Stand Placer - Responsible for most fair and proper stand and sensor placement under direction of Head Judge. 1X - No formal Judge Training is required. This is for Retail Members, Hosts, and Promoters who judge their events. 2X - Judge Training and experience required. 3X - Judge Training and experience required. Head Judge - SPL Head Judge is responsible for all SPL contests. SQL Head Judge is responsible for all SQL contests. Event Director - Responsible for all contests and MECA related activities at the event. Event Coordinator - Sets up events and oversees all aspects of scheduling and promotion in a specified area or state, working closely with the Commissioner. Responsible for all contests and MECA related activities at the event. II. Judge Guidelines Judges will make decisions fairly, with no regard for personality, system budget, brand name of equipment, vehicle, place of business, installer, or personal biases. When in a compromised position, the Judge will inform the Head Judge. A Judge will not judge family, friends, Team members, customers, or their own vehicle when another more independent Judge is available. All Judges are required to print their name or initials on all score sheets for every Competitor at every event. Judges do not wear apparel (shirts, hats, etc.) that advertises any brand names. MECA Judge shirts & hats are preferred. Judges do not eat, drink, or smoke in Competitors vehicles. Judges will use all due care and consideration for the Competitors vehicles, equipment, and property. For example, Judges must remove key chains before the event begins to prevent scratching a vehicle s interior or exterior. Judges use all due care when placing or removing the sensor/mic stand. Judges do not drive, or move, a Competitor s vehicle without permission. Judges stress safety at all times, especially when driving through the lanes and event area. Judges do not make any adjustments to the Competitors equipment. Judges may assist Competitors with adjustments during Cliniques only, making recommendations but not touching the equipment. Judges will have Competitors move wires, or property, when necessary. When a loose wire is noticed, the Competitor will be informed as soon as possible. When a verification or rule is questioned, the Head Judge should be involved for resolution. In case of a protest, it will be handled by the Head Judge, who will fill out the Protest Form and direct the investigation. Judges will not promote or solicit business or side-jobs during the event. If asked, the proper response would be to pass on a business card and ask to be contacted after the event. MECA s leagues, formats, contests, and events have unique names, i.e. Sound Pressure League, Sound Quality League, Boom & Zoom, Ride the Light, MECA Kids, Park & Pound, Modex, Radical X, RTA Freq Out, etc. MECA officials should only use MECA names for club contests. The use of trademarked or copyrighted intellectual property names from other organizations at our club contests is not permitted. SQL Judges may compete in SPL contests, and SPL Judges may compete in SQL contests, but should never be involved in verification, testing, or scoring their own vehicles.

43 Tantric Tuning Notes 1. I Got Rhythm a. Strums and plucks should be clear and clean. Listen for clarity, should be able to distinguish between the three guitars playing: one on left, one in the center, and one at the right. Left is the lead, and often heard most prominent of the three. The guitar player on the right is very lightly tapping his foot. Song is fairly simple, but unique in that the three guitars span most of the frequency spectrum. There should be no harshness and strong peaks, making it a good song to listen for overall tonality and linearity. 2. Ain t No Sunshine a. Good center vocal, life like in size with very sweet midrange tonality. The Bass guitar is left of center with full, rich tonality. 3. Won t You Come Home Bill Bailey a. This piece covers a wide range of instruments, often with solos and duets. Pay attention to each individual instrument along with its placement. Starts off with a snare drum solo located slightly left of right center. Trumpet (with a mute plug) comes in around 10 seconds at the left. At around 45 seconds a slide trombone joins in on the left with the trumpet, a tuba at left center, and a clarinet on the right. A saxophone comes in a little after 2:30 on the right as well. Banjo solo alongside to the right of the drums at right center around 3:45. Instruments are distinct and sound realistic. 4. Goodbye Porkpie Hat a. There is a great sounding guitar that comes in left of center at about 2 minutes in. There is some excellent cymbal or hihat work towards the end of the track. 5. Got to Get You Into My Life a. The vocal is front and center (however, she moves and becomes left of center after around 45 seconds). The drum kit is behind and to the right of center. The piano is just left of center and well behind the vocalist, giving a good sense of stage depth. 6. Silk Road a. This piece highlights sub and midbass frequencies. It contains some very deep and low drums starting at around 20 seconds that should be visceral. Pay attention both to lowend extension up through to the lower midrange making sure the sound is rich, full, and detailed but also not overly exaggerated or blooming. Midrange frequencies are highlighted by a Chinese flute that comes in at around 1:50 and should sound lifelike. Listen to the breath and air, and pay attention to the differentiation of tone between a traditional flute vs. a wooden one. A gong is struck at around 2:20 near the left followed by a string instrument called an erhu at left center. The erhu has a distinctive sound that is smooth and blends delicately. Chimes accentuate the high frequencies throughout this track. 7. Baker Street a. Nicely focused center vocal. There are some chimes that come it at center stage that sound great with articulation and tone. There s a harmonica to the right of center, it seems to be away from the microphone creating a bigger image. There are kongas 41

44 behind the vocalist on the left they sound very nice and discrete. There are left and right guitars. 8. Bring It on Home a. Very nice articulation to the vocalist, you can really visualize her mouth moving as she sings this song. The drum kit is very dry and just behind the vocalist. The piano occupies the left side of the stage and is very focused and discrete sounding. There are two guitars, one left and one right. The guitar on the left has some great string work and sounds very discrete. There is a second vocalist that comes in right of center. There is a sax that comes in on the left side of the stage in front of the piano and is very prominent. 9. Valse Criollo a. This track is a bit subdued to start with. It has a wind instrument right of stage, a piano that occupies center/left stage. A drum kit comes in to add some life to this truck at center stage. The song gains energy around 3 minutes in and there is also some nice cymbal work. 10. Coal Miner s Blues a. This track gives a great sense of room space. Notice how the banjo plays at left center, you can hear the echo across the room towards the right. It is a very open space with very little furniture or acoustic coverings that adds to the sound and musicality of the song. Notice the male vocal at the right that faces us and his voice echoes throughout the room. At the end of the song, listen for the decay of the banjo. It should be sufficiently long to be believable in an open, barren space. 11. Dock of the Bay a. Rhythm vocalist is far right and very full and rich in texture and tonality. The lead vocalist comes in left center. He can be heard tapping his foot at about 1:10 in. That and his breathing add up to some great realism. 12. Concerto in F Major (Spring) a. This is a great live sounding track. The violin work is very nice. There are dueling instruments at about 2 minutes in. Very full stage on this one. 13. Stepping (Isise) a. This track is great for bass and midbass articulation. Song has very good rhythm and far left and right instruments. The drums have great tonality, the mallet hitting the skin has excellent impact and very discrete sound. 14. Bass Resonance Description 15. Bass Resonance a. Great pluck, with full and rich tonality. 16. Dynamic Test Description 17. Dynamic Test a. Get this track to play loud without breaking up! 42
