Exposure to Noise in the Textile Industry of the U.A.R.

Abstract

The high prevalence of hearing loss among a sample of 117 weavers in the United Arab Republic (U.A.R.) initiated this study. Exposure to noise was evaluated in eight weaving departments, as well as in other departments in a textile plant which has been in operation for over forty years. LeveL as high as 103 dBA and an average of 98 dB, for the region 1200-4800 hertz, were encountered. Noise levels were higher in the departments where the looms operated at comparatively high speed. Noise characteristics also varied with the design of the looms for different weaving operations, e.g. normal, wool, or jackar weaving. Comparison of the noise level measured in this investigation, with the criteria recommended for hearing conservation, pointed out the need for a hearing conservation program. A control program is described, which consists mainly of the installation of sound absorbing material in the weaving departments and the use of ear protectors. Other possible control measures are also described. © 1968 Taylor & Francis Group, LLC. All rights reserved.
