Low-frequency inertial-type pressure-gradient receivers for oceanological investigations

详细

Technical solutions for the construction of inertial-type pressure-gradient receivers were developed. The manufactured laboratory prototypes with dimensions of 110 × ∅32 mm and 112 × ∅80 mm have acoustic-pressure sensitivities of 70–80 and 500 μV/Pa, respectively, in a plane wave at a frequency of 100 Hz. The performance characteristics of the hydroacoustic pressure-gradient receivers, which are used in oceanological investigations at frequencies that are substantially lower than 1 kHz, were improved.
