Ear muffs, if they fit properly, can achieve a reduction of 30 dB(A), regardless of whether they are also used as a functioning headset.

The advantages of using ear muffs are that they completely close off the ear, can potentially be used as a functioning headset for music, and provide warmth for the ears. A drawback is that they close the user off from the outside world completely and do not let normal working noises pass through.

Protecting the ears is very important. Hearing loss is one of the most frequently occurring work-related illnesses and has serious consequences. Noise damage occurs when the volume level exceeds what the ear canal is capable of handling. A good rule of thumb: if it is not possible to carry on a conversation with someone a metre away without raising your voice, the chance of developing noise-induced hearing loss is present. The noise level can be measured with a decibel meter, which will show the noise level in dB(A)..

Facts about hearing protection

A normal conversation generates a noise level of roughly 60 dB(A).

The threshold for pain is at about 120 dB(A) for most adults.

A car radio at full volume sometimes has peaks at 100 dB(A).

The danger of noise-induced hearing loss begins for employees at 80 dB(A). At levels above this, employers must make hearing protection available in accordance with the Working Conditions Act.

An employee is required to use hearing protection if the average daily exposure to noise is higher than 85 dB(A)
