laws and regulations

Occupational hearing damage is a serious problem. This is why the European Union places hearing damage in the highest category (III) of occupational risks. Indeed, hearing damage is a chronic condition, which has a great impact on your personal life. 

You can safely hear a noise of 80 decibels for up to eight hours a day (or 40 hours a week) but as soon as it increases, it quickly becomes dangerous. With every 3 decibels, the noise and thus the impact doubles. As a result, in 83 decibels, you may only work for four hours a day (or 20 hours a week). Noise at 103 decibels can damage your hearing in less than five minutes. Therefore, hearing protection is necessary to reduce the impact and danger of noise.

Rights and obligations

  • Workplaces with high noise levels (from 85 decibels) must be clearly marked. Employees are required to wear hearing protection here. From 80 decibels, employees are entitled to free hearing protection. 
  • If the noise level exceeds 87 decibels, measures must be taken to reduce it.   
  • The RI&E pays attention to noise. It establishes the level and duration of noise and the health effects. The works council must be involved in this investigation and the measures. 
  • Education about harmful noise is mandatory. To prevent hearing damage, employees have the right to have a hearing test by an expert.
