01About the competition

Not a race.
A war of sound.

Destroy The Decibel puts eligible cars on the line with nothing to prove but their voice. No lap times, no drag strip — vehicles compete through engine revving, and the exhaust note is measured using a decibel meter.

Every participant gets a maximum of one minute. The competition runs as a qualifying round followed by a final, and readings are taken strictly according to the official rules — pops, bangs and flame kits don’t count.
