Sažetak
Audiological analysis of 439 workers in the shipyard was performed. The workers worked in 13 different noisy places. The analysis was done in three ways: The intensity and quality of noise in different places was measured. Afterwards the noise was recorded on a tape recorder and then spetroscopically analysed. All workers were audiometrically examined and it was stated that 50 per cent had severe reduction of hearing. A fresh acoustic trauma was found in only 3 cases and complete unsusceptibility to noise in 4 cases. The analysis of composed audiograms shows great fluctuation of the severity of the damage of hearing depending on noise in working places. The comparative analysis of audiometric curves and spectroscopic pictures reveals a close connection between the severity of the loss of hearing and the frequencies and intensity of noise in different places of work. The main medicolegal principles are pointed out with a brief indication concerning codification. The establishment of audiological cards for all factory workers is· proposed, as well as the use o antiphons for individual protection. The authors suggest that deaf people should be employed in all the factories with extremely noisy working places. The advantages of such a policy are strongly emphasized.
