Noise is expressed in decibels, abbreviated as dB. It shows how loud a sound is. From a soft whisper to a fighter jet: our ears can perceive an enormous range of sound levels.
The decibel system works logarithmically. This means that with every increase of 10 dB, the sound becomes ten times more intense. A sound of 30 dB is therefore ten times stronger than 20 dB. And 40 dB is even a hundred times stronger than 20 dB.
Hearing damage can occur due to prolonged exposure to noise levels of 80 dB or higher. The risk of hearing damage is determined by a combination of how loud the sound is and how long you are exposed to the noise level. The hearing threshold is 0 dB and the pain threshold starts at 120-130 dB.
How long you are safe in situations with high noise levels depends on the level of the noise level. But this gradient is logarithmic, which means it increases rapidly. The safe period is therefore rapidly getting shorter, even if the level is only slightly higher. As a rule, for every increase of 3dB in volume, the safe period halves.
The image below clearly shows how much difference there is between everyday sound sources. What starts with whispering at 20 dB (A) quickly rises to values that can strain the hearing. From 80 dB (A), prolonged exposure can cause hearing damage. The sound of a lawnmower or circular saw may seem normal in a work situation, but in the long run, the strain on the ear is considerable.
Especially when working near machines or tools, it is important to be aware of noise. A small difference in dB can have a major effect on hearing stress.

In the Netherlands, employers are, according to the Working Conditions Act required to take measures to protect employees from harmful noise in the workplace. Examples include measuring noise levels, offering hearing protection and reducing exposure time. Similar obligations also apply in Belgium. According to the Codex on Welfare At work, employers must assess noise risks and take appropriate measures as soon as exposure exceeds certain threshold values. This can range from providing information and medical supervision to the mandatory provision and wearing of hearing protection.
