FIELD: hydroacoustics.
SUBSTANCE: invention relates to the field of hydroacoustics. Device for measuring parameters of bending piezoceramic transducers comprises a high-pressure hydraulic chamber equipped with an elastic membrane, sound emitter, reference and controlled converters. Emitter is a piezoceramic reversible transducer similar to the reference transducer and located inside the chamber, and controlled bending piezoceramic transducer is located on outer side of chamber, note here that hydrostatic and sound pressure is transmitted via elastic membrane.
EFFECT: possibility to measure parameters without preliminary sealing of converters.
