STANDING WAVE REDUCTION IN DIRECT FIELD ACOUSTIC TESTING
摘要
A direct field acoustic testing system includes at least two acoustical transducer groups and a signal modifier for introducing separately controllable time delays or phase shifts for each acoustical transducer group so as to provide an acoustic field conforming to a pre-determined specification with reduced deviations due to constructive or destructive interference between the acoustical transducer groups.
