Hearing loss and perceptions of noise in the workplace among rural Australians.

OBJECTIVE

To compare measured hearing levels of individuals regularly exposed to noise in their workplace to self-reported and family-reported hearing loss. To compare the attitudes and preventative actions adopted by individuals who are more aware of the potential for hearing loss to less aware individuals.

DESIGN

The project examined the perceptions of rural workers concerning noise, noise exposure and hearing. The subjects completed a 'Noise at Work' questionnaire and some demographic data at the time of audiometric testing.

SETTING

The subjects were recruited when attending their rural health clinic for audiometric testing.

PARTICIPANTS

Participants comprised 113 men and 23 women (20-65 years, mean = 39.6, SD = 11.4) working across a range of activities at different levels in their workplaces. The range in current employment was from 0.5 to 45 years (mean = 13.8, SD = 10.7).

RESULTS

Hearing tests were compared with perceptions of noise annoyance, hearing damage risk and preventative action. Self- and family-reported hearing loss and conversational difficulties in noise correlated well with measured audiograms. Perceptions of workplace noise tended to be more positive if people felt they had hearing problems. There was no difference in preventative action between those who did and did not feel they had hearing problems. Both groups rated barriers to action and lack of self-efficacy in a similar negative way.

CONCLUSIONS

There is a need for specific training to ensure that rural workers have skills to take more positive action in reducing noise exposure at work.
