Title Noise exposure and permanent hearing loss of textile workers in Thailand
Bibliographic information 1989, Vol.27, No.4, p.165-173. 8 ref.
Abstract Hearing loss induced by noise exposure in a large scale textile mill (number of workers = 1,611) in Thailand was investigated on the basis of interviews, noise measurements, and audiometric tests. The frequency of subjective symptoms relating to noise exposure was higher in the weavers than among other mill workers and office workers. The average noise levels in the weaving sections and other sections were 101.3▒2.7dBA and 89.8▒5.3dBA, respectively. The results of the audiometric tests revealed a significantly higher incidence of noise-induced hearing loss among workers in the weaving section than among other mill workers and office workers (P<0.01). Among weavers, hearing levels decreased with the longer years of work. It was found that 38.6% of the weavers never used personal hearing protection devices. It was concluded that there was a serious loss of hearing among workers in the mill. Improvements by means of integrated work organisation activities were recommended.
