Underwater radiated noise (URN) from marine vessels has grown significantly over past decades, and a growing body of research is highlighting the negative impacts this is having on marine life. The IMO has recently agreed to review its guidelines on reducing underwater noise, and a number of national and international bodies are discussing the introduction of mandatory noise targets for shipping. This talk introduces the problem of marine anthropogenic noise and discusses recent developments in our understanding of the impacts that commercial and other shipping is having on marine ecosystems. Proposed design methods and technologies for reducing URN are then discussed, focussing on emerging and novel technologies from a range of different industries.
