Underwater Hydrophone Application:

 

The SoundTrap  is a four channel digital acoustic recorder for ocean acoustic research. Its ability to record synchronous audio on four channels make it ideal for creating tetrahedral arrays for sound localisation and particle motion studies.

 

The SoundTrap can record signals from up to four hydrophones connected via the four wetplugs on the base of the recorder. The hydrophones are the pre-amplified type, and can be on long cables to enable array spacing's of several meters. Suitable hydrophones can be specified with various gain and bandwidth options.


Some Stanard Size of Spherical and Hemispherical Piezoelectric Ceramic:

 

Diameter: 5 - 40mm
Wall thickness: 0.5 - 3mm
Caliber: 5 - 8mm

Maximum radius: approx. 50 mm
