Abstract
A system and method for verification of acoustic horn performance is disclosed. This system and method includes a pressure detecting mechanism that converts at least one vibratory sound energy pulse, which is followed by at least one vacuum pulse or at least one negative pressure pulse, into a signal that is proportional to a level of sound energy, and the pressure detecting mechanism is operable to be connected to an acoustic horn. There is a measurement device that measures a value that correlates to the signal that is proportional to a level of sound energy and is electrically connected to the pressure detecting mechanism.
