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).
