Title Effect of tractor driving on hearing loss in farmers in India
Bibliographic information Apr. 2005, Vol.47, No.4, p.341-348. Illus. 21 ref.
Abstract Indian tractors do not have adequate vibration and noise attenuating design features. In this cross-sectional study, 50 tractor-driving farmers and 50 non-driving farmers matched for age, sex, ethnic group, land holding, education levels and work routines were selected from two villages. Participants were interviewed for details of work routine and noise exposures, and were subjected to audiograms. Noise measurements were taken on tractors and other agricultural machines. Self-reported hearing problems were similar (four cases each) in both groups. However, audiogram analysis showed higher prevalence of high-frequency hearing loss in cases (24) when compared to controls (14). The noise levels observed on tractors in various operations were in the range of 90-110 dB(A).
