Which group must adhere to the OSHA regulations regarding noise exposure?

The correct answer is that all employees in workplaces with noise hazards must adhere to OSHA regulations regarding noise exposure. This is because OSHA (Occupational Safety and Health Administration) sets standards that aim to protect workers from the harmful effects of excessive noise in the workplace. These regulations apply universally to all employees exposed to noise hazards, regardless of their employment status, type of industry, or whether the work is in a federal, state, or private sector setting.

By mandating that all employees in noisy environments comply with such standards, OSHA ensures that comprehensive measures are taken to assess and mitigate noise levels, implement hearing conservation programs, and provide personal protective equipment when necessary. This broad applicability is crucial for maintaining workplace safety and health, as it recognizes that noise exposure can occur in a variety of settings beyond just the obvious industrial environments.
