Aboard a ship, the noise is a sum of several factors: equipment (engines, propellers, compressors), and the waves (if the Danube is very hectic), etc. The noise leads to discomfort for the crew. This paper studies the noises on 2 river vessels traveling on the Danube between Sulina and Budapest, in February and April 2019. The noises were measured with Blue Solo sonometer and analyzed with dBTRAIT Software. The determinations were made while running, in the engine room and in the control room. To check the noise l...

This paper analyses the vibrations and noises transmitted to the seafaring staff on a cargo river ship on the Danube between Novi Sad and Sulina. The ship has 5 people as sailing personnel: 1 captain, 1 coxswain, 1 mechanic, 2 sailors. The trip was made in the fall of 2018. Parallel measurements were made on the main bridge as well as inside the engines room, in three situations: ship leaving the shore, running and mooring maneuver. We measured and calculated the main vibration parameters: Vibration magnitude r.m....
