According to EU noise directive 2003/10/EC, hearing protection must be used if the average noise level is 85 dB or higher, and it is recommended from an average level of 80 dB. However, at Hellberg we recommend always reducing noise levels to a maximum of 75 dB. This is because noise reduction can be affected by a number of external factors.
If you are unsure of the noise level, a useful rule of thumb is that if you need to raise your voice to be heard when standing one meter from someone else, the noise level is likely dangerous.
The attenuation of noise provided by your hearing protector can decrease due to insufficient fitting, misuse and poor maintenance. Long hair, beards and glasses can affect the fit of the protector. The greater the noise abatement, the more your hearing is protected. But remember that too much attenuation can be dangerous too, for example if it stops you from hearing warning signals. That is why it is very important to choose the correct hearing protection based on your needs. Our selection guide will help you find the right hearing protectors for you.
