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.
