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 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
