FIELD: measuring equipment.
SUBSTANCE: invention relates to a measurement technique, in particular, to direct measurement of acoustic signals due to pressure drop. Invention is a device for measuring pressure changes in an acoustic wave in liquid and gaseous media. Invention is a hydrophone, characterized in that it is made using an electrochemical converter that transforms the movement of the working fluid into a recorded current, providing sensitivity to pressure variations in the frequency band of 0.02–200 Hz with a high conversion factor of at least 1.5 mV/Pa.
EFFECT: invention has the following prospects of application: offshore and deep-sea seismic exploration of mineral resources, navigation and location of vessels, field technologies of the fishing industry, scientific research of the underwater biosphere, work of underwater communications, etc.
