Hearing loss from workplace noise builds up slowly and cannot be reversed. Learn how to spot a noisy workplace, reduce noise at the source, and use hearing protection properly.
Hearing damage from noise is gradual and usually painless, so many people do not notice it until it is permanent. Machinery, power tools, generators and busy production areas are common sources. The good news is that it is almost entirely preventable.
Recognize a Noisy Workplace
- Notice if you must raise your voice to be heard by someone an arm's length away.
- Pay attention to ringing or muffled hearing after a shift. These are warning signs.
- Ask for a noise assessment if you are unsure. As a common rule of thumb, protection is needed from about 85 decibels.
Reduce Noise at the Source
- Maintain machines so loose parts and worn bearings do not add noise.
- Choose quieter equipment and enclose or screen noisy machines where possible.
- Move noisy work away from people who do not need to be nearby.
Use Hearing Protection Correctly
- Choose earplugs or earmuffs that suit the noise level and fit comfortably.
- Insert and wear them properly every time you are in a noisy area, not just some of the time.
- Keep them clean and replace them when they are worn, damaged or dirty.
Take Quiet Breaks and Check Your Hearing
- Give your ears recovery time in a quiet place during long shifts.
- Have your hearing checked regularly if you work in a noisy job, so changes are caught early.
Protect What You Cannot Replace
Lost hearing does not come back. Reduce noise where you can, wear protection every time, and speak up if your workplace is too loud.
