Abstract
This study aims to evaluate the influence of pile driving noise through broadband large-area simulation for the potential offshore wind farms (OWFs) in Changhua County, Taiwan. The underwater noise simulation is based on the Range-dependent Acoustic Model (RAM) and ocean environmental inputs to broadband sound transmission calculation. The sound exposure level (SEL) and the cumulative sound exposure level with auditory weighting function for mid-frequency cetaceans in 24 hours (SELMF,24hr) are included in the noise impact assessment criteria. The results show that the SEL of piling in the offshore area of Changhua can reach 146 dB ~ 159 dB in the habitat of Sousa chinensis. Noise mitigations are recommended to reduce the impact of behavioral effects. Copyright ? 2018 by the International Society of Offshore and Polar Engineers (ISOPE)
