The competition itself is very similar to drag racing. The two contestants that are competing pull alongside the judging tower. On the judging tower, there are two light trees that are used to indicate the relative loudness of each respective vehicle. When both contestants are ready, the light trees start cycling down in a manner similar to the light trees used in drag racing. When the bottom light illuminates, the judging begins.
Spectators can see immediately who is winning by watching the light trees.
The louder a competitor's vehicle is, the higher his light tree will be illuminated. At the end of the 30 second time frame, the competitor who achieved the higher SPL wins. Drag Racing's formula for fun, excitement, and simplicity is revitalizing the sound-off community.
