CORRELATION BETWEEN HEARING IMPAIRMENT RISK AND EXPOSURE TO NOISE. PRESENT LEVEL OF RESEARCH
The present state of knowledge and recent publications which have been taken into account and which refer mainly to developments since 1975 are the basis of this study of the protection of workers against noise which may cause hearing impairment. One of the results is that the increase over the past ten years in the number of persons with impaired hearing caused by occupational noise is the result of exposure to noise in the course of previous decades. The start of the increase in cases of noise induced occupational diseases recorded in many countries is very closely connected with the start of large-scale audiometrical check-ups in the countries in question. The check-ups thus resulted in the discovery of a relatively large number of previously unknown cases. More humane criteria for the award of hearing impairment also result in an increase in the number of recognized cases of noise induced occupational diseases.
