potentially adverse effect on marine life. Noteworthy in this respect
is the International Council for the
Exploration of the Sea (ICES), whose Requirement 209 sets a limit to the level of lateral noise radiated underwater by the vessel at 1 m from the ship’s side. By means of the ICES methodology, it has been found that the noise radiated by the ship’s hull at 1 metre from the hull should not exceed 132 dB [11].
In this sense, Directive 2008/56/EC [12] comprises an international legal instrument which includes human- induced underwater noise in the definition of pollution. Also the Acoustical Society of America has published a Procedure for measuring underwater radiated noise [13].
In 2010, the DNV Classification Society issued the Silent Class Notation [14], setting different limits for each type of vessel. This
notation includes procedures for measuring underwater radiated noise.
It can be seen that regulations are being drawn up to define the requirements for new construction ships which will include limits for different aspects of the total acoustic signature (Noise and Vibration Full Signature) of each vessel: noise and vibration on board, noise radiated to the port and underwater radiated noise.
Table 4 provides a summary of noise regulations in three areas. IT can be seen that regulations on noise on board ships have been developed further than those on radiated noise in ports and underwater radiated noise, as the awareness of noise pollution from means of transport reached a highpoint in the last decade.

3.6 EUROPEAN PROJECTS ON NOISE (Related to Directive 2002/49/EC)
Ecoports: Research projects focused on the development and implementation
of tools to
environmental characteristics of ports. includes NoMEPorts
NoMEPorts: Its main objective is the reduction of noise related to health problems and annoyance caused to citizens living near industrial port areas using noise maps (with the help of specialized software for predicting noise) and a noise management system to be used specifically in industrial port areas.
The noise sources related to traffic in port areas are the roads, railway infrastructure and air traffic. Examples of sources of industrial noise in port areas are the port facilities, terminals, cargo handling and storage terminals, industrial sites, machinery and workshops, ships under construction,
repair and maintenance,
slipways and moored ships (engine noise). This
project has
characterization of the different sources of noise in a port which has shown that
carried out an analysis of the the
contribution of ships to
ambient noise is primarily due to the operation of internal combustion engines.
Harmonoise/Imagine: These projects have developed a methodology for modelling various types of
noise
sources. The Harmonoise project focuses its efforts on noise prediction methods for roads and railways, while the scope of the Imagine project extends to the sources of
A-139
