Abstract
The acoustic pollution due to anthropogenic activities has a direct impact on marine ecosystems. For instance, a high level of exposure produces behavioral changes, masking of sounds of interest, hearing losses and temporary or permanent injuries over the marine fauna. A growing social concern on this issue materialized in several national and international agreements and regulations that establish limits on the generated noise intensity. Therefore, the design of Offshore Power Stations (for win...
