Before consent is given to build in the marine environment, developers must often assess how much underwater sound will be generated during the construction and operation of a facility, and assess any potential impact on marine life. Both before and during construction, they commonly monitor and report actual sound levels to ensure they understand and adhere to thresholds.

2HR Wallingford Underwater Noise Modelling Transmission lossHR Wallingford is an international specialist consultancy and research organisation based in the UK. With a focus on water and the water-environment, its environmental experts have developed world-leading tools to model underwater sound and its potential impact on marine ecosystems.
