Abstract:

The USRL type H17 hydrophone was designed to operate in the frequency range 20 C to 150 kc, but it can be used to 250 kc. It is omnidirectional within 1.0 db at frequencies below 50 kc in the horizontal XY plane it is bidirectional in the same plane at the 0-degree and 180-degree orientations within 2.0 db in the frequency range 20 C to 150 kc. The sensitivity -94 db re one volt per microbar is little affected by temperature changes in the range from 5 to 35 deg C or by hydrostatic pressure changes up to 1000 psig. Author
