Abstract: Objective: The current study was designed to measure the hearing threshold in borma (bakery) workers and to find out the levels of hearing loss according to the duration (years) of employment in the factory. Methods: This study was conducted in 23 borma workers with an age range of 30-60 years. Pure Tone Audiometry and Distortion Product Otoacoustic Emission (DPOAE) screening was done in the workers who were working in the factories for 8-10 hours per day. Few cases were excluded from the study because the hearing loss was due to the factors other than exposure to noise. Result: The results show that the rate of hearing loss was higher in the target population. 13.04% of the workers shows a mild to moderate hearing loss at the frequencies 500, 1000, 2000 Hz in Pure Tone Audiometry. 78.26% of Borma workers were failed in the left ear and 73.90% were failed in the right ear OAE screening test and a few of them showing a hearing loss in higher frequencies. Conclusion: Due to the high exposure of noise from the bakeries, the workers are at high risk of obtaining Noise Induced Hearing Loss (NIHL). Therefore it is essential to conduct an awareness program for the workers regarding hearing loss and the use of Ear Protection Devices (EPD).
