Acoustic testing chamber

Claim 1

A CHAMBER FOR THE TESTING OF A DEVICE UNDER CONDITIONS WHICH ARE CONTROLLABLE TO SIMULATE THE ACOUSTIC ENVIRONMENT IN WHICH SUCH DEVICE IS DESIGNED TO FUNCTION, SAID CHAMBER INCLUDING A REGION WHEREIN THE DEVICE TO BE TESTED IS POSITIONED, A FIRST SOURCE OF ACOUSTIC ENERGY LOCATED WITHIN SAID CHAMBER HAVING A GENERALLY PERDETERMINED FREQUENCY RANGE, A SECOND SOURCE OF ACOUSTIC ENERGY ALSO LOCATED WITHIN SAID CHAMBER AND HAVING A GENERALLY-PERDETERMINED FREQUENCY RANGE DIFFERENT FROM THAT OF SAID FIRST SOURCE, SAID FIRST SOURCE BEING POSITIONED TO DIRECT ENERGY EMANATING THEREFROM TO THE VICINITY OF SAID TEST DEVICE ALONG AN ESSENTIALLY LINEAR PATH, SAID SECOND SOURCE BEING POSITIONED TO DIRECT ENERGY EMANATING THEREFROM TO THE VICINITY OF SAID TEST DEVICE ALONG A PATH THE INITIAL PORTION OF WHICH IS ANGULALY RELATED TO THE PATH OF THE ENERGY EMANATING FROM SAID FIRST SOURCE, AND MEANS FOR DIVERTING A PORTION OF THE ENERGY AMANATING FROM SAID SECOND SOURCE AFTER IT HAS TRAVERSED THE INITIAL PORTION OF ITS PATH SO THAT THE REMAINING PORTION OF SUCH PATH LYING BETWEEN SAID DIVERTING MEANS AND SAID TEST DEVICE SUBSTANTIALLY COINCIDES WITH THE LINEAR PATH FOLLOWED BY THE ENERGY OUTPUT OF SAID FIRST SOURCE.
