What is the OSHA standard for noise exposure?

The correct answer is that the OSHA standard for noise exposure is 90 dBA for an 8-hour time-weighted average. This standard is designed to protect workers from hearing loss due to prolonged exposure to high noise levels in the workplace. The 90 dBA threshold indicates the level of noise that can be hazardous if experienced over the standard work shift of eight hours, emphasizing the importance of monitoring and controlling noise levels in occupational settings.

The time-weighted average is a method used to determine exposure over time, which is crucial for assessing risk and implementing necessary protection measures. At levels above this standard, employers are required to take steps such as conducting noise monitoring, providing hearing conservation programs, and offering hearing protection to workers to minimize the risk of noise-induced hearing loss.

The other options presented do not align with OSHA’s established standards for noise exposure and would not adequately protect workers based on the guidelines set forth by the agency.
