Abstract

Occupational noise exposure is a significant concern for fish harvesters because it can cause severe health problems such as hearing loss, hypertension, stress, anxiety, and sleep disorders. The study investigates the perceptions of noise and self-reported hearing loss among fish harvesters in Newfoundland and Labrador. A mixed-methods research was conducted. A pre-validated survey tool was adopted to assess perceived noise risks and self-reported hearing loss. Semi-structured telephone interviews were conducted to explore noise exposure and associated health problems as well as obstacles and challenges for fishing workers to take noise reduction measures. Data were collected through 76 survey responses and twelve interviews. Through measuring the perceived benefits, barriers, and self-efficacy score (2.3 to 2.9 out of 5), this research finds a moderately positive attitude of harvesters toward noise reduction and hearing loss prevention. A high perceived attitude and susceptibility score (3.9 to 4.5) suggests that fish harvesters disliked the loud noise and were susceptible to hearing loss. Most interviewees agreed that their workplace is noisy. A conflict between vessel safety and individual health was observed, as participants reported that the reason to avoid wearing hearing protectors is due to various other safety concerns. Participants believe that increasing education, awareness, and training can reduce noise exposure and prevent hearing loss.
