What type of sound levels require mandatory hearing protection?

Mandatory hearing protection is required for sound levels exceeding 90 dB because this level poses a significant risk of hearing damage. At sound levels of 90 dB and above, the potential for noise-induced hearing loss increases substantially. Prolonged exposure to such intense noise levels without adequate hearing protection can lead to permanent hearing impairment over time.

Regulatory standards, such as those set by the Occupational Safety and Health Administration (OSHA), specify that hearing protection must be used when noise exposure reaches this threshold to safeguard workers' auditory health. This practice helps minimize the risk of adverse health effects associated with high levels of noise exposure, ensuring a safer work environment for individuals who may be subjected to these loud environments on a regular basis.

Other sound levels mentioned do not necessitate mandatory hearing protection as urgently as those exceeding 90 dB. Levels exceeding 70 dB might be considered moderate noise, and while they can be disruptive, they typically do not lead to immediate hearing damage without long-term exposure. Sound levels exceeding 80 dB may call for the use of hearing protection in certain circumstances, mainly if exposure is prolonged or frequent, but they do not universally mandate it like the 90 dB level does. Levels below 85 dB generally
