Most of the textile industries in developing countries are facing a big problem of noise pollution and vibration. The assessment of noise pollution and vibration in textile industries has been the aim of this study and Textile Mill 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 Textile Mill 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 Mill. In this regard, a programme which includes different methods of how to control the problem has been proposed for conserving hearing and vibration at the factory. The methods include modification of the noise and vibration source by providing viscoelastic epoxy resin sound damping coating, repair of machines, and periodic audiometric testing. This paper presents an efficient method to determine sound power levels (PWLs)measured by sound level meter(SLM) near the noise sources generated by the simultaneous operation of Terry towel machine and Time–frequency analysis, including the wavelet transform, is one of the new and powerful tools in the important field of structural health monitoring, using vibration analysis. Commonly used signal analysis techniques, based on spectral approaches such as the fast Fourier transform (FFT), are powerful in diagnosing a variety of vibration-related problems in rotating machinery
