Abstract
Hearing loss due to chronic exposure to noise, the Noise Induced Hearing Loss (NMI has been associated with industries for many years and NIHL has become an alarming situation for the authorities all over the world. The size of the problem in Bangladesh is not known. Textile industry is one of the most noise producing industries. So. this study was undertaken in one of the textile industries at Narshindi to find out the prevalence. type and severity of NIHL among the workers. The working population of this study industry was 2100 out of which 100 were randomly selected for the study. Our of 100 subjects. 26 (26%) were found to have NHL The industry had six departments where study was carried out. The noise intensity levels of each department were measured. Highest intensity of noise was in generator department and lowest in administration department, 97 dB to 10 dB and 45 dB to 50 dB respectively. Average duration of exposure to noise of each subject at various departments in a working day wax between 11.33 and 12.17 hours. No NIHL was found in administration department. The highest percentage (53.33%) of NHL was found in generator department. Dyeing department having highest &trariau of employment of 9.58 years had N1HL in 43.75%. Factors that were found to be important for developing NIHL were intensity or loudness of noise to which the person was exposed and the cuomdative duration of exposure. More than fourth of the employees had NIHL who worked at a noise intensity level 82 dB to 102 dB in contrast to none who worked at 45 dB to 50 dB.
