If your hearing is damaged by noise, your hearing will never be the same again

If you work with noise levels in excess of 80 dB(A), there is a risk of you suffering from chronic hearing impairment. The louder the noise, the greater the risk
Damaged hearing first affects how you hear speech and music – and impairs your quality of life.
When you are exposed to noise, you are affected by noise here and now or noise over time.
With noise here and now, you can measure it in dB(A) by your ears and find out straight away whether you are working with tools that are too noisy.
With noise over time, you can measure by your ears over the course of an entire working day to see whether you are being exposed to too much noise (and not just from the gaffers). The limit for noise is max. 85 dB(A) over a full 8-hour day.
