Abyssens has designed its own range of underwater acoustic recorders. They enable the marine environment to be monitored using passive acoustics, with pre-processed data displayed in post-processing via dedicated software. Abyssens has also developed software to make acoustic analysis accessible to as many people as possible for regulatory monitoring of noise from construction sites at sea. On request, Abyssens offers its expertise in the specific analysis of acoustic data such as the detection of marine mammals, acoustic modelling and impact assessments.
