Noise-induced hearing loss is one of the more common types/causes of hearing loss. Exposure of high levels of noise for years in the workplace can lead to noise-induced hearing loss. This could be of a mild, moderate or even severe degree. This post covers how companies can work to reduce work-related noise-induced hearing loss.
In basic terms; within the inner portion of our ears are tiny ‘hair-cells’ that are essential in receiving information from incoming sound waves. This information then travels via nerve pathways to the brain for interpretation.
Sustained exposure to high levels of noise (over 85db) can damage these hair cells. Long-term exposure to loud noise overworks the hairs in the ears and can cause them to die.
It is not only long-term exposure that can cause hearing loss, but a 'sound trauma' can also cause damage. A 'sound trauma' is a burst of sound, such as an explosion. They can cause temporary hearing loss, as the ear hairs bend with the effect of the loud noise. Once the hair becomes straight again hearing returns. However, if the noise causes too much damage some hairs will die and repeated exposure can destroy the hairs causing permanent hearing loss.
To put levels of noise into perspective - drill can make 100 - 110 db of noise, a quiet office makes 40 - 50 db of noise.
Based on the 2005 government noise regulations, businesses should monitor and actively protect their employees from the risks of noise-induced hearing loss.
The Control of Noise at Work Regulations (2005) aims to protect employees from exposure to noise levels in excess of 85 decibels.
For more information on work-related noise-induced hearing loss head to the Health and Safety Executive website.
