The paper presents the study of underwater noise generated by moving ships associated with the vibration measurements and analysis inside the hull. A particular area of the noise generated by moving ships to the environment are shipping lanes and approaches to ports. In 2012-2015 the Polish Naval Academy in Gdynia participated in the study noise of ships as a participant in the European Defence Agency project SIRAMIS. The study focused on the signature response analysis on multi-influence sensors. During the sea trials it was measured over sixty of vessels, and the data analysis found that significant differences exist not only between different classes of vessels but also for a vessel. To explain these differences, measurements of vibrations inside the ship's hull were made. The tests took place on one ship that sailed to Gdynia port many times. The results of comparing the underwater noise of the ship with the vibrations of the mechanisms and the hull plating are presented in this article.
