This document specifies the relevant characteristics and properties of hydrophones in the frequency range 1Hz to 500kHz, and specifies how to report these characteristics. It does not cover performance requirements for specific hydrophone types, or for specific hydrophone applications. However, guidance on the choice of a hydrophone with appropriate performance for a specific application is given in an informative annex.
This document is applicable to:
hydrophones employing piezoelectric sensor elements, designed to respond to sound pressure in water and measure underwater acoustical signals;
hydrophones with or without an integral pre-amplifier.
