HYDROACOUSTIC TRANSDUCER FOR SEA MEDIUM Russian patent published in 2000 - IPC

FIELD: hydroacoustics, applicable for measurement of pressure level of hydroacoustic noise of surface and underwater floating facilities in the conditions of sea medium, it is also applicable for protection of floating facilities against hydroacoustic detection systems. SUBSTANCE: the hydroacoustic transducer has a hydrophone and a container with electronic equipment, the latter is covered with a sound-absorbing shell in the form of acoustoelectronic cells adjoining one another, whose outputs are connected to resistors. The energy of acoustic waves getting on the container is partially suppressed. EFFECT: reduced getting of rereflections of acoustic beams on the hydrophone from the container, enhanced accuracy of hydroacoustic measurements. 11 cl, 8 dwg
