What is the OSHA permissible noise exposure related to?

The OSHA permissible noise exposure is specifically related to decibel levels. OSHA has established guidelines that indicate the maximum allowable noise exposure levels in the workplace, measured in decibels (dB). The permissible exposure limit for noise is generally set at 90 dB for an 8-hour workday, with an increase in permissible noise levels as exposure time decreases. Understanding these decibel levels is crucial for assessing workplace noise hazards and implementing effective hearing conservation programs.

While sound power, frequency of sound, and health implications of sound exposure are important considerations in noise exposure regulations and assessments, they do not directly define the permissible thresholds established by OSHA. The primary focus of OSHA's guidelines is on the intensity of sound, quantified in decibels, to protect workers from hearing loss and other associated health risks.
