In this paper an attempt has been made to evaluate the hearing loss of workmen (subjects) in an open cast Chromite mines with respect to age, working experience and work stations. The age group 50–60 years is found to be the biggest age group suffering significant hearing loss on both the ears. Also, the Work Zone area is found to be most significant area affecting hearing loss on both the ears. However, the subjects having experience of 30–35 and 25–30 years have the most significant hearing loss on the left and right ears, respectively. Also, there is no significant difference of hearing loss exhibited by the subjects on both ears at the age group of 50–60 years and to the subjects working in the work zone area.
