Noise-induced hearing loss and hearing protection: Attitudes at a South African coal mine.
Kavitha Naicker
PMID 38299534WHAT IT FOUND
Coal miners reported strong knowledge of hearing loss risks and high intention to wear protection.
However, 86% found earmuffs uncomfortable, and self-reported compliance may overestimate actual use, as observed rates in similar studies are often lower than reported.
Key findings
01Participants displayed positive attitudes towards most aspects of hearing protection, with 96% agreeing they could protect their hearing by wearing devices and 98% intending to wear them in noisy conditions.
02A major barrier to use was physical discomfort, with 86% agreeing that earmuffs put too much pressure on their ears.
03Self-reported adherence was high, with 95% agreeing they wear hearing protectors whenever working around loud noise, though the authors note this may differ from observed compliance.

What it does not show
The study was conducted at a single coal mine, so results may not apply to other industries or mines. Data collection occurred at a mass gathering, which may have influenced responses due to social desirability or peer pressure. The response rate was 79%, but the sample size fell short of the calculated 306, potentially introducing selection bias. Self-reported compliance may not match actual observed behaviour, a discrepancy the authors acknowledge.

The easy way to misread this
Do not assume that because miners report high intention to wear hearing protection, they actually do so consistently. Self-reported compliance in this study was very high, but the authors note that previous research shows observed compliance is often much lower than what workers report.
