Abstract:
The use of reflectors to control the distribution of the Sound Pressure Level SPL in sonic test chambers is investigated. The goal is to obtain more realistic SPL distributions on the test object. It is concluded that the use of reflectors will not increase the SPL on a test object unless the reflector and test object are in the near field of the sound generators. The results of the study are applied to the Air Force Flight Dynamics Laboratorys AFFDL Sonic Fatigue Facility at Wright-Patterson Air Force Base. Design charts are presented that relate predicted SPL distributions to reflector size and positioning. Author
