The standard that addresses permissible noise levels in the workplace is OSHA 1910.95. This regulation specifically outlines the requirements for employers to control noise exposure to protect workers' hearing. It sets permissible exposure limits for noise (measured in dBA, A-weighted decibels) and mandates monitoring, hearing conservation programs, and training for workers exposed to high noise levels.

Understanding the significance of this standard is crucial as it helps to prevent noise-induced hearing loss, which is one of the most common occupational illnesses. By adhering to these regulations, employers create a safer work environment and promote the health and well-being of their employees.

The other choices do not pertain to noise exposure standards. For instance, OSHA 1910.120 deals with hazardous waste operations, 1910.22 refers to walking-working surfaces and their safety, and 1910.134 addresses respiratory protection. These standards serve different safety and health purposes but do not cover noise regulation in the workplace.
