What is the allowable daily exposure limit established by OSHA for noise levels?

The allowable daily exposure limit for noise levels, as established by OSHA (Occupational Safety and Health Administration), is set at 90 dB (A) for an 8-hour workday. This standard is crucial for protecting workers from the harmful effects of prolonged exposure to high noise levels, which can lead to hearing loss and other health complications.

The 90 dB (A) threshold represents a level at which hearing conservation measures should be implemented. If noise exposure exceeds this level, employers are required to take action, such as monitoring noise levels, providing hearing protection, and offering auditory training to minimize the risk of hearing damage for employees.

The basis for setting this limit involves extensive research into the relationship between sound levels and the risk of noise-induced hearing loss, making it a critical safety standard in many industries.
