An acoustic transducer includes a housing (18) having means (22) for dispersing internal reflections within the housing to minimize the incidence of such internally reflected acoustc pulses on the transducor (14) itself, thereby avoiding the generation of spurious electrical signals for transmission to the translating circuitry. In one embodiment the operating end of the housing includes stepped annular surfaces (24) which provide sharp angles of incidence to the internal reflections to direct the away from the transducer (14).
