Work environments can be noisy places. Employers often attempt to reduce noise levels by engineering controls for equipment or work environments. However, when noise levels become hazardous, the Occupational Safety and Health Administration (OSHA) requires employers to have a program in place to protect workers' hearing. This program is called an hearing conservation program and is specifically regulated by OSHA in every state.
These programs are designed to help protect employees' hearing by controlling noise when possible, limiting exposure to noise otherwise and monitoring hearing for changes that might be due ot workplace noise.
Hearing conservation programs are for your benefit!
Many employers would probably offer the same protections as a mandatory hearing conservation program, even if it were not required by law. However, OSHA exists to make sure that all companies reduce risks as much as possible for employees placed in hazardous environments.
If a hearing conservation program is required in your workplace, it is to make sure that you have the option of keeping your hearing for your whole life. Your employer is being mandated by OSHA to reduce noise levels, watch your hearing, and take responsibility if your hearing should be damaged by workplace noise.
If you have any questions about your hearing, your workplace environment, or your rights as an employee, talk to an audiologist or physician specializing in ears (otologist/ENT). The goal is to keep you hearing well into your retirement years so you can continue to enjoy life the way you should.
