Aim: To evaluate the association between hearing loss and duration of the noise exposure. Methods: After taking the ethical permission this study was done in the department of community medicine. We included 50 male drivers who were exposed to high intensity noise for more than 7 hours a day over a period of 9 years and more of job. 35-55 age group people were included in this study. Family history and personal details regarding any ear problems and injury, neurological problems, use of ototoxic drugs etc. was noted. The individuals were also asked any use of ear protection component by them. Result: 50 male were included in this study, 44.55±10.55 mean age of the person. 62% of the individuals were observed to be having sensorineural hearing loss. They were further divided as low, average and high problem on the basis of recordings of BERA. Among the 50 participant 20% had low, 24% had average and 20% had high level of hearing loss.5 The intensity of hearing loss was more profound in participant serving for very long time. 66.67% of the participant who were exposed to loud noise for more than 18 years had high intensity of SNHL, while only 10% of them working for 10-14 years duration had high intensity of hearing loss. Conclusion: We concluded that the highly exposure of the noise has been correlated with the intensity of the hearing loss. So regular audiological checkup is very important for all the people who working in high intensity noise area.
