    Abstract: The paper presents the design and testing of low cost autonomous underwater acoustic listeners (UL) for the measuring of the ambient noise in the marine environment. The testing of these stations has been performed in the framework of the European Commission funded project “QUIETMED” aiming at the homogenization of the practices to be adopted by European countries around the Mediterranean basin in order to fulfill the requirements of the Marine Strategy Framework Directive (MSFD) of the E.C, with respect to the monitoring of the continuous noise in European waters. The continuous noise is mainly due to the marine traffic (shipping noise) so the post-processing of the measurements performed during the tests, were adopted to low frequency ranges. Large part of the instrumentation was self-made at the Hydroacoustics Laboratory of FORTH. The underwater listeners were calibrated in the water tank of the Laboratory, in a semi-anechoic chamber and in situ in every sea trial. Two types of deployments were tested. The first one, with all the instrumentation suspended from a ship in a single mooring is appropriate for short term measurements (typically for one day). The second one involves an autonomous mooring which stays in water for a longer period and is appropriate for medium term measurements. The pilot experiments that were held in two spots in the north and south coasts of Crete, are briefly presented and some typical examples of the way that post-processing of the measured acoustic data result in graphs for general use, are also shown.
