Why do people wear ear muffs?
People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or dBA. Hearing protectors reduce the noise exposure level and the risk of hearing loss. If hearing protection is required, then a complete hearing conservation program should be implemented.

What is the lowest level of noise that can cause hearing loss?
The lowest level of noise that can cause hearing loss is 85 dB. Prolonged exposure to noise at this level or higher can cause permanent damage to the tiny hair cells in the inner ear which are responsible for transmitting sound signals to the brain. In general any noise louder than 80 dB can cause hearing loss so it is important to protect your hearing when exposed to these levels of sound. Noise levels below 70 dB do not typically cause hearing loss. Noise levels between 70 and 85 dB can cause hearing loss with extended unprotected exposure. Noise levels above 85 dB can cause hearing loss with shorter unprotected exposure.It is important to be aware of the noise levels around you and to take steps to protect your hearing. If a noise is too loud wear hearing protection such as ear plugs or ear muffs. Additionally it is important to take regular breaks away from noise to allow your ears to rest.
