Noise Modelling and Assessment

At Seiche, we are at the forefront of addressing the growing concern about the impact of underwater sound on marine life. With increasing regulatory focus across the world, it has never been more critical to accurately and robustly assess the potential effects of offshore and coastal development on our marine ecosystems.

Our Expertise

Seiche’s dedicated team of acoustic specialists brings unparalleled knowledge and experience to noise modelling and assessment. Leveraging a highly integrated approach, we combine expertise in underwater acoustics an in-depth understanding of marine life and practical industry experience. This synergy ensures that our solutions are not only scientifically robust but also practical and tailored to industry needs.

Our cutting-edge underwater acoustics modelling and assessment tools, such as our line array model for piling, are grounded in the latest scientific advancements and have been praised by regulators and their advisors. Whether assessing the effects of piling, blasting, or other offshore activities, our methods are precautionary, robust, and designed to withstand regulatory scrutiny.

Practical Solutions, Clear Communication

At Seiche, we go beyond simply identifying problems. Our extensive experience across multiple offshore industries allows us to deliver clear, actionable solutions that streamline the regulatory process. We excel at communicating complex acoustic issues in an accessible manner, reducing consenting risks by ensuring regulators and stakeholders fully understand assessment outcomes.

Our collaboration with the industry, regulators and the scientific community helps us stay aligned with the latest scientific research and best practices. This commitment to innovation and precision is evident in our proven track record of successful projects and strong client relationships.
