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.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...
