Personnel working in designated noise hazard areas should be entered into the hearing testing program if sound levels exceed what maximum decibel level?

The correct maximum decibel level at which personnel working in designated noise hazard areas should be entered into the hearing testing program is 84 dB. This threshold is based on occupational safety guidelines that help prevent hearing loss due to prolonged exposure to high noise levels. At 84 dB, the risk of hearing impairment increases significantly if individuals are exposed to this level for extended periods without adequate hearing protection.

Therefore, monitoring and enrolling personnel in a hearing conservation program at this level is a crucial preventative measure to ensure their auditory health and comply with safety regulations. Keeping track of exposure levels through regular hearing tests can help identify any potential issues early and facilitate timely intervention.
