- Scope
- This standard specifies two measurement methods for the insertion loss and echo reduction of underwater acoustic material samples: the pulse tube method and the free field method. The measurement results can be used for the design basis and performance evaluation of sonar domes, sound-permeable windows, reflector baffles and anechoic coverings. This standard applies to homogeneous and uniformly layered samples of hydroacoustic materials.
