Underwater Acoustics

Technical underwater acoustics services supporting marine research, environmental impact assessments, and offshore construction projects in the Western Indian Ocean.

Underwater noise is a critical environmental and permitting risk for marine construction projects. Pile driving, dredging, and offshore installation activites can generate sound levels that pose risks to marine life and may delay or prevent project approval if not properly assessed and mitigated. We provide regulator- and lender-compliant underwater acoustics services, combining advanced noise modelling, noise monitoring and practical noise mitigation solutions to support efficient, environmentally responsible project delivery.

From modelling to monitoring and mitigation — we turn underwater noise challenges into solutions.

We apply underwater acoustics both in applied project support (modelling, monitoring & mitigation) and in scientific research and conservation contexts.

Acoustic Modelling

We perform project-specific underwater noise modelling using dBSea, an industry-recognized software for pile driving, dredging, and other marine construction activities. Model outputs include transmission loss maps, sound exposure levels, and scenario comparisons, tailored to project-specific regulatory and environmental assessment requirements. This helps developers and regulators evaluate potential impacts and design effective mitigation measures.

Acoustic Monitoring

We carry out underwater noise measurements tailored to each project, including baseline assessments and monitoring during construction activities such as pile driving and dredging. Data collection ensures compliance with environmental regulations and supports informed mitigation planning and reporting.

Software: primarily PAMGuard

Acoustic Analysis

We transform collected underwater acoustic data into clear insights, calculating key metrics such as Sound Exposure Level (SEL) and Peak Sound Pressure Level (SPL). Our analysis supports environmental assessments, regulatory submissions, and noise mitigation design. Results are presented in concise, stakeholder-ready formats to facilitate informed decision-making.
