BACKGROUND: Occupational noise-induced hearing loss (NIHL) occurs in many industries despite interventions such as hearing conservation programmes. AIMS: To determine the actual and reported use of hearing protection devices (HPDs) in noise-exposed gold mine workers and their reported knowledge, attitudes and practices relating to NIHL and HPDs. METHODS: A cross-sectional descriptive study was conducted in which 101 noise-exposed mine workers were interviewed and their use of HPDs observed. RESULTS: Thirteen percent of respondents erroneously indicated that their workplaces were not noisy, 16% did not appreciate noise as a hearing loss hazard, 6% did not know that HPDs protect hearing and 3% believed that HPDs did not protect hearing. While 93% of respondents reported using HPDs, only 50% were observed to be doing so. Observed use was less among lower skilled workers, and, despite training, 8% of respondents claimed never to have been informed about the benefits of HPDs. Consistent and continuous use was reported by 24% and 31% of respondents, respectively. Reasons for not using HPDs included discomfort. Most respondents (57%) preferred training methods other than the current computer-assisted training. CONCLUSIONS: The persistence of NIHL may be explained by limited use of HPDs, along with the suboptimal knowledge of noise as a hazard, workplace noisiness and the benefits of HPDs among some workers. Concurrent with engineering controls, a range of HPDs should be available free of charge, and HPD training reviewed particularly for lower skilled workers.
