How to predict and improve the quality of the soundscape in a context of coastal and marine development?

Taking the environment into account remains a necessity for the economic and social development of industrialized countries. Process intelligence is no longer limited to improving performance, but also to the ability to monitor and regulate the impact of human activities on the marine and terrestrial environment. Ports are major interfaces between human activities and the marine environment. Ports also appear to be prime candidates for implementing effective measures to reduce or limit impacts and encourage a responsible attitude of users towards the environment. Using advanced technologies, Terre-Mer-Veille in collaboration with Sorbonne University, offers solutions to study the acoustic impact on the marine environment of coastal and marine development projects before their start and to control the acoustic environment during their development. Upstream of the work, we propose a predictive approach based on digital acoustic simulations adapted to the bathymetric context, the physical and chemical characteristics of the marine environment and the maritime work scenarios transmitted upstream. During the work phase, monitoring noise levels makes it possible to check the consistency of the observed data with the predictions and to discuss possible Avoidance-Reduction-Compensation measures (ERC eq. in French legislation).
