Abstract
Introduction: Noise is defined as aperiodic complex sound. Noise is a common cause of hearing the loss in adults. Hearing loss due to injurious noise at the workplace is referred to as occupational noise-induced hearing loss (ONIHL). Research has shown that sounds >85 dB can cause damage to our hearing. Policemen are the people who are exposed to traffic noises than any other people and are the least to care an audiological evaluation. Aim: The aim of the study was to study the incidence of NIHL in police constables and to study the effect of age, personal habits such as smoking/drinking and medical conditions such as diabetes and hypertension on hearing loss. Materials and Methods: The subjects were 50 police personnel (43 - males and 7 - females). A detailed history was taken regarding the number of years of service, past ear disease, and past medical conditions affecting hearing. All the subjects underwent routine ear nose and throat examination and pure tone audiometry to identify detectable hearing loss. All the subjects had normal hearing on recruitment. Results: NIHL was present in 94% of subjects. The severity of NIHL was mild in 26% of subjects. Conclusion: NIHL is preventable. The NIHL is common in traffic policemen. Early detection and prevention of hearing loss will play a major role in improving the quality of life in traffic police.
