Discription of chapter
In this chapter, the indicative levels of noise in a textile-manufacturing unit are presented.
Aim of chapter is to familiarize all the involved parties with the Occupational health and Safety in the sector of Textile Industry with noise and to propose measures and methods of prevention.

M04.07.01 Hearing problems and noise existence in the Textile Industry
- Hearing problems are caused by the high levels of noise (above limit values) that are observed in almost all stages of the production process
- High levels of noise remain also in the modern units in textile industry
- The consequences depend mainly on the use of personal protective equipment
- It is remarkable that workers in maintenance have been observed having higher frequency of acoustic lesion, obviously related with their working conditions, as well as with improper use of individual personal hearing protective equipment
- For workers in spinning sector it should be taken into account that intense mobility is observed, consequently most of them have only few years of employment, question that probably is related with the phenomenon of healthy worker. The same seems to be in effect with regard to the hearing problems, but the results are not comparable. The percentages appear to be resembling, with regard to elements for professional loss of hearing compared to older studies
- The confrontation of noise is particularly practically difficult and so noise can also be found in modern units too
- In most stages of production the use of personal protective equipment is essential for the confrontation of noise consequences
