At what noise level does OSHA recommend hearing protection when using compressed air tools?

OSHA recommends hearing protection when noise levels reach 85 dB to safeguard workers' hearing health. At this level, unprotected exposure can lead to hearing loss over time, as prolonged exposure to sounds at or above this decibel level can cause damage to the auditory system. This guideline is based on research identifying that sustained exposure to noise of 85 dB or higher significantly increases the risk of noise-induced hearing loss. Using hearing protection at or above this threshold ensures that workers are provided with adequate precautions against potential auditory injuries associated with the use of loud machinery, such as compressed air tools.

Other decibel levels, while still concerning, do not trigger the same level of immediate recommendation for protective measures within workplace safety guidelines. Thus, 85 dB serves as the critical point at which organizations are advised to implement hearing conservation programs and require personal protective equipment for their employees.
