Nowadays, the interest on the acoustic noise emission level of vessels is increasing worldwide. In fact, the European Union (EU) promoted the Marine Strategy Framework Directive (MSFD) to monitor the Good Environmental Status (GES) of the EU seas. The measurement of the underwater acoustic noise is expensive and usually is not feasible. For this reason, … Read more
Anthropogenic activities in the marine environment are generating a continuous growth in the pollution related with different kinds of radiated energy. The cruise ships traffic is configured nowadays as one of the activities of most rapid growth, especially in environments as the Mediterranean Sea. Starting from these premises, this research has as its main objective … Read more
Shipping traffic is recognised as the main man-noise source of the anthropogenic noise generated in the marine environment. The underwater acoustic pollution is increased due to the increment of the human activity at seas supposing a threat for marine habitats. The ship as acoustic source must be understood and controlled to manage the maritime areas … Read more
Anthropogenic noise is a growing threat to marine life due to the incrementation of human activity in the marine environment. In Europe, the Directive 2008/56/EC of the European Parliament and of the Council was published with the aim of establishing a framework for community action in the field of marine environmental policy. The directive introduces … Read more
Anthropogenic noise is a growing threat to marine life. The human interaction with the marine environment is entailing a continuous growth in the Ambient noise levels. This effect is particularly noticeable in shallow water areas which are characterized by concentrating a high level of activity in a wide range of fields such as fishing, tourism, … Read more
Currently, the impact of underwater noise on marine fauna and flora is an area of great interest, especially in the European Union after the publication of the Framework Directive in 2008. The study of the impact generated by underwater noise involves the development of different disciplines including acoustics, biology, physics, signal processing, etc. The objective … Read more

SIRAMIS is a project coordinated by the European Defence Agency standing for Signature Response Analysis on Multi Influence Sensors. As most of the international trade is carried out through marine routes, it is important to evaluate the vulnerability of the merchant vessel fleet to sea mines in order to be able to limit the potential … Read more
The noise generated by the ships’ machinery and transmitted through its structure constitutes one of the main sources of noise radiated by ships. The estimation of radiated noise, and with it the control of underwater acoustic pollution generated by ships, can be carried out by applying a function that relates it to the measurement of … Read more
The Transfer Function (TF) relates the structure-borne noise level of the hull with the Underwater Radiated Noise (URN). Therefore, the acoustic noise generated by the vibrations of the hull of a ship could be estimated from real measurements of the structure-borne noise levels of the hull by applying the TF in real time. This function … Read more
