  Abstract: The impact of shipping noise on the marine environment awakes an increasing interest in our society. Protection measures are topics in different environmental groups. International regulations are recommended and implemented in various directives. The main topic is the reduction of anthropogenic underwater noise radiation. The validation of reduction measures and the given underwater radiated noise limits of a new ship has to be confirmed on sound ranges. However, reported results are affected by the individual properties of the individual range.\nDuring an international campaign two research vessels, the CFAV QUEST and the RV PLANET, were noise ranged at shallowed and deep water ranges in Europe in a short time period using predefined configurations and procedures. In addition, numerous accelerometers were installed on board of the two vessels to monitor the structure borne noise simultaneously during the trials at the sound ranges. \nThis presentation focuses on the comparison of the results of deep underwater ranges in Scotland and Norway and the shallow underwater range in Germany, Eckernfoerder Bay. Conclusions and recommendations are extracted from the effects and results. \n
