Definition of DB drag racing
dB drag racing is a competition rewarding the person who can produce the loudest sound inside a vehicle. The "dB" means decibels of sound pressure level (SPL). In these competitions, SPL of over 140 decibels is common; and the international record in 2003 was 171.5 dB, with records as high as 180 dB claimed more recently.
Competitive vehicles can range from a small vehicle with a single amplifier and subwoofer up to a large van with dozens of amplifiers and subwoofers powered by dozens of car batteries and with upgraded electrical wiring and alternators.
There were 10,000 competitors in 2003 and 300 "races". U.S. National Championships were held in Tennessee.
