Abstract
A method and apparatus for testing individual hydrophones mounted on seismic streamer cables. An irregularly shaped chamber is provided which can be clamped around the cable containing the hydrophone to be tested. An acoustic transducer, such as a loud speaker, provides an acoustic pressure signal inside the chamber. The response of the hydrophone being tested is compared to that of a reference hydrophone mounted within the chamber.
