New Underwater Noise Propagation Model

HR Wallingford worked with Loughborough University to develop HAMMER (Hydro-Acoustic Model for Mitigation and Ecological Response), an underwater noise propagation model which predicts noise levels at distance from a point source. The tool can also be used to investigate the impact of underwater noise on species behaviour. Further development of the tool is underway in collaboration with Bristol and Exeter Universities to determine behavioural response of fish species to underwater noise.
