Section 1 - General Rules
1-1	Competitors may use the program material of their choice while competing. Additional Guidelines: The program material being played must originate from a source unit that is specifically designed for installation and operation in a 12-Volt auto sound environment. This includes cassette decks, CD players and changers, DVD players and changers, VCR's and VCP's, MP3 units, AM / FM / Satellite radio tuners, and any other playback device that is specifically designed for installation and operation in a 12-Volt auto sound environment. The program material may consist of music, test tones, or any other type of recorded audio signal. The program media may be from a commercial source (such as a CD you purchase) or a custom, homemade recording. Tone generators, frequency multipliers, harmonizers, etc. are prohibited. Exceptions: Competitors must use the officially approved dB Drag Racing competition CD at all multi-point events. If an event takes place prior to the release of the official CD, then the previous year's CD may be used in the interim. (Please visit www.termpro.com/dbdrag/rules for more information regarding the current season's officially approved CD.) Competitors are limited to playing frequencies between 20 and 80 Hz at all multi-point events. If a competitor's highest SPL is achieved at a frequency below 20 Hz or above 80 Hz, then that competitor's score will be disallowed. If the violation occurs during the qualifying rounds, the competitor may be granted a retry at the sole discretion of the head judge. If the violation occurs during the elimination rounds, the competitor will be eliminated from the competition, regardless of the competitor's score.
1-2	Adjustments to the sound system may be made while the vehicle is being metered as long as no other applicable rules are violated during the adjustment process. (Metering is the process where the Sound Pressure Level or SPL of your vehicle is measured.)
1-3	The contestant's vehicle may be running while in the judging lanes as long as the following conditions apply: The contestant is competing in the Super Street or Extreme Divisions of competition. Contestants competing in the Street and Street Max Divisions are prohibited from running their vehicles while in the judging lanes. (Please see Section 2 for a complete description of the Competitor Classification System.) Operation of the vehicle or sound system must not endanger the judge, competitor, spectators, or any real or personal property on the premises. The vehicle's parking brake must be set. The wheels must be chocked. The hood must be closed. The maximum engine idle speed must not exceed 2000 RPM. A remote "engine kill switch" must be easily accessible from outside of the vehicle for those competitors that are bolting (clamping, strapping, etc.) the doors of the vehicle closed while in the judging lanes. It is the competitor's responsibility to comply with the conditions listed above. Competitors found to be in violation of one or more of these conditions may be eliminated from the competition.
1-4	The contestant must be outside of the vehicle while the vehicle is being metered and all doors, windows, and other openings to the vehicle must remain closed during this time. Exception - Competitors may remain inside of the vehicle during metering provided: They wear adequate hearing protection at all times. Removal of the hearing protection while inside of the vehicle will result in immediate disqualification. The competitor's maximum SPL never exceeds 140 dB. A measured SPL in excess of 140 dB will be recorded as 140 dB. The competitor must sign a dB Drag Racing entry form that includes a waiver stating that the competitor understands that "exposure to high sound pressure levels may result in temporary or permanent hearing loss".
1-5	When the SPL metering process begins, contestants will have 30 seconds to achieve their highest Sound Pressure Level (SPL). The SPL metering equipment will record and save each competitor's high score during this 30 second judging interval.
1-6	Contestants may not open their vehicle during the metering process. If a contestant opens his or her vehicle while being metered, the competitor's score shall be nullified. If the violation occurs during the qualification rounds, the competitor may be granted a retry at the discretion of the head judge. If the violation occurs during the elimination rounds, the competitor in violation shall forfeit the round.
