ABSTRACT:
A spherical wave generating diffuser positioned in front of the sound emission side of a sound source. The diffuser comprises an inner horn and an outer horn positioned concentrically around the inner horn. The diffuser generates pseudo-spherical waves centered on the inner horn because the emission speed of the sound waves emitted from between the outer horn and the inner horn are slower than the emission speed of sound waves emitted from within the inner horn.
