In the aquatic environment, sound is the primary channel for the transfer of information and energy. We offer comprehensive hydroacoustic solutions, adapted to both restricted and open waters.
From quantifying the noise generated by human activity —vessels, port operations and infrastructure— to the precise characterization of non-anthropogenic ambient background noise: biophony and geophony.
At ROUSSEAUX we offer comprehensive hydroacoustic solutions adapted to both restricted waters —rivers, estuaries, navigation channels and port areas— and open waters: open sea, coastal zones and deep waters.
Rivers, estuaries, river channels and port basins where acoustic propagation is confined by shallow depth, topographic boundaries and complex interaction with the sediment bed.
Continental shelf, oceanic zones and protected marine areas where free-field dynamics and surface reflections prevail.
Environmental baselines to understand natural background noise, before human activity enters the scene.
We measure and map geophony —wind, waves, currents, rain— and biophony: the communication of cetaceans, marine mammals, fish and benthic fauna.
We determine the ambient noise level (background noise) prior to the development of infrastructure projects, dredging or the opening of new shipping routes.
We assess acoustic health in vulnerable habitats to determine masking thresholds and loss of biological communication space.
We certify the acoustic signature of vessels both in open sea and in restricted waterways, under the international ISO 17208-1, 2 and 3:2025 standard, using adjusted propagation loss models (SSCI and Lloyd's Mirror).
We identify the mechanical causes of excess noise to optimize fuel consumption.
We design and implement technical and operational roadmaps to reduce the acoustic footprint (URN-RP).
We link the reduction of anthropogenic noise with hydrodynamic efficiencies that represent fuel savings of between 5% and 15%.
We measure and monitor your fleet's underwater radiated noise following IMO guidelines, generating the traceability required for environmental certifications and for impact studies on marine fauna.
Backup of every raw audio file with SHA-256 hash digital signatures for environmental compliance audits.
High-precision hydroacoustic instrumentation, calibrated to IEC 60565 standards.
Reducing anthropogenic noise translates into hydrodynamic efficiencies and measurable fuel savings.
