When the workplace has a constantly high level of noise, it can harm the person’s hearing. The risk of hearing damage exists, if the noise level exceeds 80 dB(A). Noise level is too high when you have to shout loudly to the person standing ½–1 metres from you in order to make yourself heard. Noise can damage hearing also then, when machines producing very loud noise are used for a short time, or machines making a weaker noise for a long time.

The daily noise level influencing employees during an eight-hour workday may not exceed 85 dB(A). During the working environment risk analysis, the employer is obliged to measure the noise and, depending on the measurement results, evaluate the possible health damage to employees.

If noise cannot be decreased with joint protective measures, the employer must enable the use of individual hearing protection equipment (headphones, earplugs) to employees. If the noise contact level is 85 dB(A) or greater, the use of hearing protection equipment is mandatory.

If employees come in contact with noise in their work, health checks at the occupational health doctor must be organized. Health checks enable to diagnose noise-related hearing damage in its’ early stages.
