适用范围：Establishes measurement procedures for calibrating underwater electroacoustic transducers. Both primary and secondary calibration procedures are specified for frequencies from a few Hz to a few MHz. Procedures are specified to determine measurable characteristics of free-field receive voltage sensitivity, transmitting response, directional response, voltage coupling loss, impedance, and equivalent noise pressure. Measurement uncertainty analysis is introduced and identifies common error sources.
