The results have been interpreted in terms of the potential avoidance response this noise might have on selected marine species. Field measurements were carried out using calibrated hydrophones along four transects extending up to 30 km from turbine positions, supplemented by background noise recordings, literature review, and comparative analysis with established injury and behavioral criteria (US NMFS, Southall et al. 2007, UK BERR). The study employed both unweighted and species-specific dBht and M-weighted acoustic metrics to analyze noise exposure, accounting for hearing sensitivities and including predictive modeling for impact range estimation. Results showed low likelihood of lethal effects but potential for physical injury within 13 m, auditory injury for harbour porpoise up to 570 m, and behavioral avoidance at substantial distances (up to 17 km for porpoise).

This report presents some of the peer reviewed data on hearing sensitivities of fish and marine mammals that is thought to be the most reliable. For many species, however, there is either no sensitivity data available, or the data that is available is of poor quality. The approach that has been undertaken in this study is to base the assessment of underwater noise on the perceived level of sound for a number of species of fish and marine mammal that are present in the region, and other UK waters, and for which a good quality audiogram is available.
