Introduction: The acceptable noise level (ANL) measure is a subjective way of identifying how much of noise a person is able to put up with while listening to speech. Individuals with low ANL were observed to be satisfied hearing users than the individuals with high ANL. However, the reason for large individual variations of the measure is still not well understood. Exposure to noise may be one such factor that would affect the ANL which was never explored. Among the individuals who are exposed to noise, majority are exposed to occupational noise. Traffic police is such a working population who is exposed continuously to traffic noise during their duty hours. Hence, the present study was planned to investigate ANL measures in traffic police officers that might further provide insight toward the heterogeneity of the measure. Methods: A total of 38 participants were divided into two groups. Group 1 consisted of 19 traffic police officers with minimum of 5 years of job experience and Group 2 consisted of normal hearing individuals without any noise exposure. All the participants underwent routine audiological evaluations followed by ANL testing. Results: The mean ANL obtained in both the groups was statistically compared. The results revealed that the traffic police officers yielded better ANLs than participants in Group 2. Conclusion: This ability of traffic police officers to put up with more noise while listening to speech may be attributed to their long-standing experience in listening to wanted signals in noise.
