In situ recorded data are analysed from processing routines developed by us, applied to numerous databases and regularly published in specialized journals. The methods used are based on the publications most recognized by the underwater acoustics scientific community and are regularly updated according to the progress of research in this field.
Ambient noise
Characterization of the ambient noise and its spatio-temporal variability.
Characterization of acoustic sources
Description of the sounds emitted by a specific sound source (frequency content, levels received, levels emitted at the source).
Modelling of acoustic propagation
Simulation of the acoustic propagation of sound signals in the environment taking into account its environmental characteristics.
Acoustic footprint and potential impacts
Estimation of the project’s acoustic footprint and prediction of the potential impacts on surrounding wildlife (marine mammals, fish).
Analysis of soundscapes
Identification and quantification of the different contributors to soundscapes (biophony, anthropophony, geophony).
Marine mammals detection
Study of the activity of marine mammals in a specific area (attendance, functional role).
