    Abstract: The establishment of binding MSFD thresholds values for descriptor 11 has enabled new achievements in the further development of the assessment of the environmental status in relation to underwater noise. Valuable lessons learned have been gained meanwhile, particularly in the context of initial implementation approaches in regional waters and research projects. Gaining first practical experience with the implementation of assessments under the MSFD threshold umbrella has also shown that there are still challenges to be tackled. Here we present results obtained from current data and research projects on impulsive and continuous noise aiming towards the further improvement of assessing pressure and impact on marine mammals. These include finding from the analysis of different acoustic evaluation criteria and the standardised description of sound sources serving as input data for noise assessments. These could be made available through national and regional noise registers.
