Underwater acoustics. Hydrophones. Properties of hydrophones in the frequency range 1 Hz to 500 kHz Ingestion-build-46800 10 provides you with reagents1 Scope This document specifies the relevant characteristics and properties of hydrophones in the frequency range 1 Hz to 500 kHz, 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
