The maximum duration an employee can be exposed to 97 decibels without hearing protection is what?

The maximum duration an employee can safely be exposed to noise levels of 97 decibels is indeed three hours without hearing protection. This determination stems from occupational safety standards that aim to prevent hearing loss due to excessive noise exposure.

The limits set for noise exposure are generally based on the intensity of the sound measured in decibels and the duration of exposure. The criteria typically follow a model where an increase in noise level decreases the allowable exposure time. For sounds at 97 decibels specifically, the regulatory guidelines indicate that three hours of exposure is the maximum without risking significant hearing damage.

This understanding is essential for both employers and employees, as it informs the creation of safety protocols and the implementation of hearing conservation programs in work environments where high decibel levels are present.
