ABYSSENS, underwater acoustic equipments

Abyssens low power underwater acoustic recorders have large and adaptable storage capacities (up to 16 TB). Therefore they are made for deployments at sea from two weeks to six months of continuous recording in coastal environment or deep sea on request.

The high dynamic range (110 dB) of our recorders allows you to monitor both the ambient noise and high level sound sources like human generated noises at the same time, for example the ship radiated noise or the acoustic levels emitted during works at sea such as pile driving and drilling.

The high frequency version (up to 200 kHz) can record a large set of sources like vocalizes and clicks of marine mammals such as harbor porpoises.

MOBI is a buoy dedicated to real-time monitoring of underwater acoustic sounds. High acoustic performance is available with 24 bits raw data, 110 dB dynamic range, listening up to 200 kHz.

While recording, an embedded analysis is carried out to allow the real-time transmission of acoustic levels and alerts in the event of a threshold being exceeded.

With a long data transmission range without additional subscription costs, energy self-sufficiency and a large storage capacity of up to 16 TB, MOBI is suitable for coastal or deep sea applications, for short missions or long-term PAM (Passive Acoustic Monitoring).

Acoustic data analysis software

Sea Works Acoustics Analyser

They talk about it.

Sea Works Acoustics Analyser is the acoustics post-processing analysis software. It is autonomous and therefore dedicated to everyone, even to non-acoustician people. It automatically publishes regulatory reports.

It allows the evaluation of ambient noise and acoustic levels generated during pile driving over different monitoring sessions.

DaViS DAta VIsualization Software

A post treatment dynamic visualization of the data is possible with the dedicated software: DaViS.

It displays the spectrogram, the temporal evolution of Sound Pressure Level (SPL), the Power Spectral Density and the third octave band levels. In addition, this software allows audio listening.
