||Occupational hearing loss among selected farm tractor operators employed on large multiproduction farms in Poland
||1998, Vol.11, No.1, p.69-80. Illus. 23 ref.
||45 farm tractor drivers from multiproduction farms were examined in order to estimate the degree of occupational hearing loss. Hearing loss of over 20dB was noted for 56% of operators within the highest frequency range of 3, 4 and 6 kHz, and for 22% of operators in the medium frequency range of 0.5, 1, 2 and 3 kHz. No hearing loss was observed in the control group. In the group of operators under 35 years of age a statistically significant correlation was observed between hearing loss and the length of employment in agriculture, whereas in the group of workers over 35 years of age hearing loss was more strongly correlated with age, although this was not statistically significant. Results confirmed that detected hearing loss among operators of farm tractors was caused by exposure to occupational noise on farms. Topics: age-linked differences; agricultural operations; audiometric tests; epidemiologic study; hearing loss; hearing threshold; length of service; noise level; noise; Poland; sound frequency; tractors.
