To determine effective methods for enabling workers to reduce noise exposure.

Hypotheses:

1. That training in hearing loss prevention that uses a workshop format, involves workers in generating their own solutions for hazard reduction, and discusses noise in the context of other workplace hazards will be effective in reducing workers’ noise exposure levels.
2. That the effectiveness of hearing loss prevention training is affected by personal factors such as workers’ perceived self-efficacy, noise annoyance, barriers, benefits and susceptibility to hearing loss.
3. That the effectiveness of hearing loss prevention training is affected by the safety culture in the workplace.
