Material Detail

Noise and vibrations generated by ships affect a wide range of receivers: crew and passengers inside the vessel, inhabitants of the coastal areas and marine fauna outside it. Recent studies suggest that a large percentage of people living in urban areas close to harbours and a number of marine species, at different evolutionary levels (in particular mammals and cephalopods), suffer from ship N&V emissions in air and in water. The present degree of knowledge of the phenomena involved in the noise emissions inside and outside ships is quite different, as a result also of the time elapsed since the negative effects were realized and therefore studied. The development of the normative framework in the various areas reflects these differences, but there are expectations for improvements on all fronts that need to be supported by the scientific community presenting the latest research results in this particular field of acoustics. Papers dealing with the following topics (but not limited to) are welcome: ship airborne noise, ship underwater noise, ship vibration, underwater vehicle vibration and noise, vibration control and noise reduction methods, low noise design, experimental methods and signal processing techniques for underwater noise and its control, harbour noise.
