    Abstract:
    A total of 328 blacksmiths was examined so as to obtain and analyse the physical parameters of noise exposure for its hygienic evaluation and norm setting. The noise parameters were found to vary according to different criteria if underassessed by means of existing standard 3223-85. Comparative study of hearing loss in the blacksmiths according to a standard 1999 revealed a hyperaggressiveness of impulsive noise in close connection with both noise level and length of service. Impulsive noise was recommended to be evaluated according to the peak level and quantity of impulses, but the basement of MAL is possible with the help of standard pattern while the criteria as length of service, quantile of population and the grade of hearing loss are chosen.
