Title

Excessive Sound Noise Risk Assessment in Textile Mills of an Ethiopian-Kombolcha Textile Industry Share Company

Pages

  105-114

Abstract

 In countries like Ethiopia, the textile industries are facing a big problem of Sound noise pollution. In these countries, the industrial hearing conservation program is not yet clearly developed. Thus, characterizing excessive noise pollutions in textile industries have been the aim of this research project and Kombolcha Textile mill (KTM) is chosen as the case study. The study is concerned with noise exposure and its characteristics at the different section of the Textile mill. Before the actual excessive noise level measurements are collected in the Textile mill, the main areas where measurements are done have to be identified. This is done by prior physical observation and A-Weighted time-averaged Sound pressure levels (L_Aeq) survey. More than one hundred walkthrough measurement points are done inside the Textile mill. These data are analyzed using MATLAB software packages. Based on our analysis, the spinning and the weaving sections of the mills with its unit processes are identified as potential noise pollution in the factory. On these sections, the measurements are done for 4– 5 h/d. The instrument used for measurements is a precision integrated portable professional Sound level meter. The findings reveal that the KTM employees work in hazardous environments above 90 dB, which is the recommended safe limit of noise in the working environment for 8 h used in international standard. As a result, engineering and administration programs which include different methods of how to control the problem has been recommended for conserving hearing at the KTM.
