Which organization regulates the U.S. industry regarding noise control?

The Occupational Safety and Health Administration (OSHA) is responsible for overseeing and regulating workplace safety and health in the United States, which includes noise control in various industries. OSHA establishes permissible noise exposure limits to protect workers from hearing loss and other auditory issues caused by excessive noise levels in the workplace. They provide guidelines and enforce standards that employers must follow to minimize noise hazards.

OSHA's regulations also include requirements for noise monitoring, hearing conservation programs, and employee training on how to handle and mitigate exposure to high noise levels, which places it as the key agency related to noise control regulation within occupational settings.

The other organizations mentioned, while they have important roles in public health and safety, do not primarily focus on workplace noise control regulations. The Environmental Protection Agency (EPA) deals more broadly with environmental issues and pollutants, the Mine Safety and Health Administration (MSHA) focuses specifically on mining safety, and the National Institute for Occupational Safety and Health (NIOSH) conducts research and makes recommendations related to workplace hazards, including noise, but does not enforce regulations like OSHA does.
