A Molecular-Electronic Hydrophone for Low-Frequency Research of Ambient Noise in the World Ocean

This work is devoted to the problems of elaboration of the instrumental basis for low-frequency sensing of ambient noise of the ocean. The experimental data of testing of the technical parameters of a molecular-electronic hydrophone are given. The amplitude-frequency and noise parameters of prototypes have been studied. The operation of a hydrophone with a frequency range of 0.02–200 Hz and sensitivity of 0.75 mV/Pa is described. Ambient noise was measured with the use of correlation analysis.
