What is the permissible exposure limit (PEL) per OSHA standards?

The permissible exposure limit (PEL) set by OSHA standards for noise is 90 dB(A) for an 8-hour workday. This standard is based on the understanding that exposure to sound levels at or above this threshold can potentially lead to hearing loss and other auditory ailments over time. The 90 dB(A) limit is established to protect employees in occupational settings where noise exposure is a concern, ensuring that the duration and intensity of exposure do not reach harmful levels.

Understanding this PEL is crucial for hearing technicians, as it serves as a guideline for monitoring workplace noise and implementing hearing conservation programs. Regular assessments and the use of hearing protection devices become essential when noise levels exceed this limit, helping to mitigate the risks associated with prolonged exposure to high levels of sound.
