This paper analysed the noise from a pusher ship on the Danube. The measurements were made according to “Ship Vibration and Noise Guidance Notes”. The analysis was performed on a pusher ship (2400HP), with 6 barges, moving upstream, from Sulina (km 0) to Bazias (km 1072). The noise was measured with BlueSolo01dB type sound meter, placed in the engine room, the main deck and the rest room. So, in the first case, inside the engine room, the Daily noise exposure (LEP,d) was 92 dB; in the second case,on the main deck, LEP,d was 88dB and in the third case, inside the rest room, LEP,d was 83dB. For the entire week LEP,w was 92dB. It can seen that (for the noise over the entire duration of the trip) the Lower Exposure Action Value (LEP,d = 80dB given by Directive 2003/10/EC) is exceeded by 15% and the Upper Exposure Action Value (85dB) by 8.23%. For this reason, hearing protectors are recommended.
