The hearing tests were made on 1197 persons in two metal mines working under noise exposure. A worker who showed hearing loss over 20db at even one frequency were treated as occupational deafness.<br>1) Occupational deafness was found in 35.1% of 1197 workers.<br>2) The rate of occurence showed high rate in the workers serving for long years.<br>3) Similarly the rate of occurence showed a high rate in the older workers.<br>4) The grade of hearing loss had a tendency to vary from slight to worse in proportion to the age 20_??_60 years old.<br>5) The grade of hearing loss had a tendency to vary from slight to worse in proportion to the number of working years 6_??_35 years.<br>6) The distribution of high grade hearing loss and slight grade was shown nearly in the same in age group, but was not the same in the group years of service.<br>7) In one persons who was examined through 1, 2, 3, 4 years, the grade of hearing loss had a tendency to become slightly worse in proportion to the number of working years, at the same time the variance of hearing loss increased.<br>8) The variance of increased hearing loss is believed to be due to individual differences.
