SEASONIC Digital Hydrophone

SeaSonic Digital Hydrophone

SeaSonic Digital Hydrophone is designed for underwater noise monitoring and underwater noise recording either with a personal computer of integrated in a ROV or AUV or UUV or onboard an oceanographic buoy. SeaSonic is equipped by the following sub-systems:

- Sensor Cetacean Research Technologies' CR1/CR1A or CR3 hydrophones 
(Other hydrophones as per customer requirements are applicable to integrate)
- Hardware Signal DAQ-4 Data Acquisition Board (with Analogue Signal Conditioning) 
- Software SignalSOFT

Hydrophone signal is conditioned in analogue domain (preamplify, filter and control automatic gain) and digitized by embedded Signal DAQ-4 data acquisition module in the underwater housing. SeaSonic is controlled by the software SignalSOFT where operators can start / stop data acquisition and data recording and can set the gain of each channel of Signal-DAQ-4 board. SeaSonic is also controlled to start / stop data acquisition and data recording by means of a scheduled or programmed operation via SignalSOFT Software.
