The air compressor creates instant air pressure to the horns. Since the pressure is created so fast there is no need for a storage tank as on Semi Trucks and RVs. Although the pressure is very low (12-15 psi) it delivers a large volume of air (3 CFM or cubic feet per minute). This low-pressure high volume air supply causes the diaphragm inside the horn to vibrate at a high rate of speed or *frequency* The exact speed at which it vibrates is varied by the length of the horn or trumpet. Together the horn set produces an extremely loud 128-decibel warning blast. This is approximately 4 times louder than most electric motorcycle horns, which usually rate at 87 decibels.
