C57
The C57 is a hydrophone specifically designed to record sound signals from marine mammals. It has an 4 m long cable and can be connected directly to an I/O interface through the attached jack connector. It requires a 9 V block battery for operation, which can be easily connected. Thus, it is very quickly ready for use and can be launched directly from board into the water.
Sensitivity
A typical sensitivity of -167dB re 1V/μPa over a bandwidth of 15Hz to 45kHz ±3dB can be achieved. This includes the pre-amplfier inside the C57 itself. Further details and sensivity curves can be found at the website of Cetacean.
Calibration
Currently, no calibration procedures are available.
Equalization
Currently, no equalization data is available.
Typical Use Cases
Often used in underwater communication due to the easy handling and rugged casing.
