Most of the textile industries in developing countries like Tanzania are facing a big problem of noise pollution. In most of these countries, the industrial hearing conservation programme is not yet established. The assessment of noise pollution in textile industries has been the aim of this study and Friendship Textile Mill (FTM) is chosen as the case study. The investigation was concerned with the noise exposure and its adverse effects to workers at the mill. The findings revealed that about 30% of the FTM employees are working in hazardous environments of above 90 dB, which is the recommended safe limit of noise in the working environment for 8 h used in Tanzania. In this regard, a programme which includes different methods of how to control the problem, has been proposed for conserving hearing at the factory. The methods include the use of hearing protective devices, modification of the noise source, repair of machines, and pre-employment and periodic audiometric testing.
