ABSTRACT:
Acoustic wave "diffractor" labyrinth(s) are positioned obliquely in front of sound producing transducer(s) to cause very wide angle dispersion of the sound waves projected from said transducer(s) into said labyrinths. The labyrinths may consist of a complex of bent and folded chambers. This system causes depolarization of the sound waves projected from the transducer(s).
