Abstract
The electroacoustic transducer disclosed is of double mass loaded piezoelectrically driven type particularly adapted to high power sonar array application. For reducing transducer sensitivity to interference and noise of frequencies at and below the transducer moving assembly mounting resonance, without significant impairment of transducer efficiency even at high power levels in the active mode operating frequency bands, the transducer moving assembly mounting resonance is damped by provision of a resistive coupling which in its preferred form comprises a lossy rubber ring compressed between the transducer housing and the inertia mass. Corona suppression means effective at high power levels of operation as described also are disclosed.
