Sažetak

Audiological analysis in a textile factory with 800 workers was carried out. Electroaccoustical measurement showed the values of 102-105 din-phons. Spectroscopical analysis gave an ascendent curve with the top 93 din-phons in the area of 1 600-4 000 Hz. 609 workers were audiometrically examined. Only 51 workers, i. e. 8%, were found to have normal hearing and in 53 workers excessive susceptibility to noise with severe lesions of hearing, in spite of a very short stay in the factory was found. The analysis has shown many different types of lesions of hearing (assimetric, unilateral and atypic). In a special group there were workers with active or adhesive otitis media but normal hearing, in spite of the long period of time spent in the factory, so that it semed that otitis had played a protecting role in the appearance of accoustic trauma. As regards preventive and prophylactic measures, a system of audiological examination is set forth.
