Underwater acoustics is our core business
From data analysis to acoustics modeling, Abyssens extended its know-how in underwater acoustics. Its experience in this field enabled it to gain an in-depth knowledge in regulatory regards. Its skills spread to active acoustics (tomography and active localization).
- Radiated noise estimation and spectral analysis
- Automatic detection and classification
- Modeling of radiated noise and creation of noise maps
- Spatio-temporal monitoring and statistical analysis
- Automatic characterization of the contributors (biophony, anthropophony, geophony)
- Impulsive sound detection
- Regulatory thresholds exceedings computation
- Impact areas assessment
- Vocalizations and clicks detection
- Estimation of levels heard by marine mammals
- Identification of impact and masking areas
Multidisciplinary skills
Thanks to the achieved projects, Abyssens extended its skills to transverse fields complementary to underwater acoustics.
