GB/T 7967-2002 in English

《GB/T 7967-2002声学 水声发射器的大功率特性和测量》由TC17（全国声学标准化技术委员会）归口，主管部门为中国科学院。
本标准规定了表征水声发射器在实际工作状态下功率发送性能的基本电声参数及其测量方法。
本标准适用于压电型、磁致伸缩型等水声发射器、也适用于由这类发射器所构成的水声发射器阵。
本标准中的测量方法适用于在大功率下测量水声发射器，也适用于测量或试验非大功率激励下的水声发射器。

Scope

This standard specifies the basic electroacoustic parameters and their measurement methods that characterize the high-power transmission performance of underwater acoustic transmitters under actual working conditions. This standard applies to piezoelectric, magnetostrictive and other underwater acoustic emitters, and also applies to underwater acoustic emitter arrays composed of such emitters. The measurement methods in this standard are applicable to the measurement of underwater acoustic transmitters under high power, and also applicable to the measurement or test of underwater acoustic transmitters under non-high power excitation.
