NOISE LEVEL ANALYSIS ONBOARD A VESSEL X DURING SAILING AT SEA

Abstract

Naval vessels sacrifice some characteristics, like the comfort of the crews. This research will give compliance with the human factor standards in terms of noise onboard Vessel X. The research methodology developed in this study applies to all classes of ships through the available international standards. The study took full-scale noise onboard measurements for Vessel X in various compartments according to IMO compartments subdivision standards. Analysis for the most suitable international standards to be used in the measurement onboard is conducted first. Noise levels measurement is conducted in various spaces on all decks accessible to the crew to give a complete and adequate picture of the levels of noise onboard. The measured noise levels compare with current limits for working and living spaces using the international standards for noise (DNV, IMO, NIOSH, and DOSH). The measurement data analyzed and identifies the crucial spaces onboard regarding the crew's noise exposure and acoustic comfort while working onboard. Results show that this ship's noise level exceeds the standards set at the international level and is at risk of having an impact like motion sickness on the ship crew.
