the study was conducted on a group of 90 traffic policemen aged 20-50 years and working in and around patiala district to assess their knowledge, attitude, and practices toward the ill effects caused by traffic noise on health. the subjects were required to fill up a questionnaire regarding their self‑assessment of hearing ability, noise‑related attitudes, and the use of personal protective equipment such as earplugs. the mean age of subjects was 39.8 ± 5.80 years, while the mean duration of exposure to traffic noise was 10.56 ± 6.43 years. only 5.5% subjects felt that their hearing was below average. as many as 61% subjects had work‑related tinnitus. it was observed that none of them had ever used ear plugs, mainly due to their non availability. the self‑assessment of hearing by traffic policemen indicated that most of them had normal hearing. however, to find out the exact number of cases with hearing impairment, further evaluation with audiometry is recommended in them.
