Exposure to noise:
High levels of noise have been observed in most of the units engaged in the textile industry, particularly those in developing countries. In the long run, exposure to high noise levels has been known to damage the eardrum and cause hearing loss. Other problems like fatigue, absenteeism, annoyance, anxiety, reduction in efficiency, changes in pulse rate and blood pressure as well as sleep disorders have also been noted on account of continuous exposure to noise. Lack of efficient maintenance of machinery is one of the major reasons behind the noise pollution in a majority of the units. Though it causes serious health effects, exposure to noise is often ignored by textile units because its effects are not immediately visible and there is an absence of pain.
A study of 77 employees in textile mills in Nagpur was conducted by Ruikar MM, Motghare DD and Vasudeo ND. This study revealed that 76.6% of the employees were at risk for developing noise-induced hearing loss. The study of Indian textile units by R. Steinberg, J. Hannak and K. Balakrishnan indicated that 21.3% of the workers studied suffered from noise-induced hearing loss.
