What is the OSHA exchange rate for noise exposure?

The correct answer reflects the established exchange rate for noise exposure under OSHA regulations, which is set at a 5 dB exchange rate. This means that when an employee is exposed to continuous noise, for every increase of 5 decibels in sound level, the permissible exposure time is halved. For example, if the noise level is 90 dB, workers can be exposed for 8 hours; if the noise level rises to 95 dB, the exposure time should be reduced to 4 hours to maintain safe hearing levels.

Understanding this exchange rate is crucial for implementing effective noise control measures in Occupational Safety and Health Administration (OSHA) regulated environments. It serves as a guideline for employers to assess employee noise exposure and to implement adequate hearing conservation programs. This exchange rate aims to protect workers from hearing loss due to hazardous noise levels in the workplace.
