DEVICE FOR MEASURING UNDERWATER NOISE OF WATERCRAFT AND SYSTEM FOR CHECKING OPERATING STATE THEREOF

摘要

FIELD: physics, acoustics.;SUBSTANCE: invention relates to hydroacoustics and can be used to monitor the noise emission level of an underwater object in a natural water body. The method includes raising a measurement module from watercraft, said measurement module being fitted with hydrophones and used to measure the noise emission level of the watercraft. The measurement module is fitted with a system for checking the operating state thereof without dismantling the device.;EFFECT: enabling measurement of the noise level of underwater watercraft directly from the watercraft.;13 cl, 3 dwg
