Underwater Noise
Expert Underwater Acoustic Assessment.
We initially developed our interest in underwater noise through the development of the dBSea software, but have continually increased our consultancy capability in the previous number of years.
We now regularly carry out noise measurements and modelling from all projects which generate noise underwater including off shore wind farms, harbour expansions, piling, cable laying or shipping traffic
Modelling experience
We deliver quantitative underwater noise modelling using the dBSea modelling platform, partially developed by Irwin Carr. Modelling accounts for bathymetry, seabed properties, sound speed profiles, and source characteristics to predict noise propagation across marine environments. This enables assessment of impacts on marine mammals and fish species using recognised acoustic thresholds and hearing group weightings.
Monitoring
We undertake underwater noise monitoring using calibrated hydrophone systems to characterise vessel traffic, dredging, and other anthropogenic sound sources. Monitoring programmes are designed to capture real‑world sound signatures, providing a reliable evidence base for impact assessment and mitigation.
