ActiveAcoustics—Calibration of hydrophones—Part 1:Procedures for free-field calibration
声学 水听器校准 第1部分：自由场校准方法
Application Summary AI generated
This standard specifies the procedures for calibrating hydrophones in a free-field environment, such as an anechoic water tank or open-water test site. It is applied in underwater acoustics metrology to ensure accurate measurement of sound pressure levels for hydrophones used in sonar systems, marine research, and naval defense applications. The standard is critical for laboratories and manufacturers performing type approval or periodic verification of underwater acoustic sensors.
