Noise sources and hazardous noise levels on fishing vessels: The case of Newfoundland and Labrador's fleet

Fishing is one of the most important and riskier working activity in the province of Newfoundland and Labrador (NL) Canada. Fish harvesters are exposed to many occupational hazards on board fishing vessels. Amongst these, the combination of high noise levels and prolonged exposure on fishing vessels is thought to be responsible for noise induced hearing loss. Also, high noise levels in the crew spaces are known to reduce comfort. This research provides a first look at noise sources and noise levels on fishing vessels in NL.The study first looked at data on fishing vessel types and identified the characteristics of the most common fishing vessels. Vessel inspections identified sources of noise and structural layouts by vessel type. An in-situ program was then carried out to measure noise during seven fishing trips on board different vessels fishing for cod, whelk, lobster and crab, each characterized by different fishing gear and operations. During the trips, noise levels were measured and subsequently processed to identify the main noise components. The research identified the propulsive engine and auxiliary machinery as the main steady state noise sources and showed that the noise is beyond recommended levels for most spaces on the vessels.
