OSHA requires employers to implement a hearing conservation program when noise exposure is at or above 85 decibels averaged over 8 working hours, or an 8-hour time-weighted average (TWA).
In which work area must you wear hearing protection?
Hearing protection should be required when: Employees are exposed to workplace noise during an 8-hour work shift, in which the noise averages 85 dBA (50% dose) or greater; An employee has not yet had a baseline audiogram established (in a work environment) averaging 85 dBA or greater; or.
Where is hearing protection essential?
People should wear a hearing protector if the noise or sound level they are exposed to is close to or greater than the occupational exposure limits (OEL) for noise. For most jurisdictions, this occupational exposure limit is 85 decibels (A-weighted) or dBA.
What is earmuffs where it is required?
Earmuffs are used to protect the ears from environmental noises produced by machines, transports, equipment and nature. In most communities, noise level is limited to around 55 decibels. In the workplace, earmuffs are generally required when noise levels are higher than 80 decibels.
What does OSHA say about hearing protection?
Under the promulgated regulation [29 CFR 1910.95(i)(1)], OSHA requires that: Employers shall make hearing protectors available to all employees exposed to an 8-hour time-weighted average of 85 decibels or greater at no cost to the employees. Hearing protectors shall be replaced as necessary.
What level of hearing protection do I need?
85 Decibels (dB) – the “Action Level” where hearing protection is required. 90 dB – the OSHA, 8 hour average exposure limit. 100 dB – exposures longer than 15 minutes are not recommended. 110 dB – regular exposure of more than 1 minute risks permanent hearing loss.
Why hearing protection is so important?
Loud noises are the number one cause of hearing damage, even more so than old age. Hearing protection is the only way to keep your hearing from becoming prematurely damaged. Both earplugs and earmuffs are sufficient at protecting your ears from loud noises and can prolong your ability to hear sounds clearly.

Hearing PPE must be regularly inspected and maintained
Personal hearing protectors must be regularly inspected and maintained to ensure they remain in good, clean condition. The inspections should check that: ear-muff seals are undamaged. the tension of headbands is not reduced.
Are earmuffs safe?
When working in hazardous noise, workers are at risk of hearing loss every time they lift their earmuffs to speak to a coworker, readjust their PPE or even to cool down on a hot day. Reality: Although earmuffs do not go inside the wearer’s ears, they should be cleaned on a regular basis to ensure hygienic use.
