Özet
In industry increased mechanisation results in increased noise levels. Operation of textile machines carries a high risk of hearing loss. In this study the evaluation of textile worker's noise induced hearing loss was reviewed cross sectionally. The hearing of 260 textile workers exposed to noise levels between 85-95 dB(A) in carpet and cotton textile factories was assessed by means of air and bone conductance audiograms obtained. The subjects were grouped into five hearing categories according to hearing thresholds at 125 to 8000 Hz with Klockhoffs classification. The prevalence of the grade-3 hearing loss was 47.92% and grade 4-5 was 9.21% on exposed subjects in both factories. There was significant differance between exposed and unexposed control subjects working in the same factories (p
