Noise in the workplace has become a major socio-political problem in recent decades. Noise-induced hearing loss remains one of the leading occupational diseases. In Germany, several million workers are exposed to noise at work that is harmful to their health and, in particular, their hearing. Every year thousands of new cases of occupational noise deafness are reported.
Noise therefore poses a significant risk to health, including the ears, and a burden on performance, with noise disturbances leading to adverse effects even at low levels. Noise reduction, on the other hand, leads to improved performance and the avoidance of errors. This is particularly noticeable by a reduced error rate in production.
Noise emissions should be taken into account when purchasing machines. Sound emission can be reduced by retrospective measures such as sound insulation capsules, silencers, etc. In addition, physiological factors are positively influenced by measures to reduce noise. This contributes, among other things, to the fact that workers become ill less frequently.
Noise reduction at the source is the most effective of all measures. The machine manufacturer is obliged to indicate the noise emission of his machine which is determined according to the applicable standards.
Indoors, the decrease in noise level is lower than outdoors. It can be improved through sound-absorbing walls and ceilings, and raised by acoustic screens.
At the work place with high noise intensity, ear protection (ear muffs, ear plugs) is the only option to reduce the noise for a short period to a level that is acceptable and tolerable from the health point of view. However, since hearing protection has considerable disadvantages - such as impairment of communication, risk of accident, sweating, feeling of pressure, obstruction of work - and the protective function of hearing protection can only be ensured to a limited extent, noise reduction through technical measures has priority.
