Introduction: This present study is an attempt to study the demographic characteristics of individuals presenting with hearing loss in a peripheral tertiary care hospital using the available database of pure tone audiometry results. Materials and methods: A retrospective, observational, descriptive study was conducted over a period of 5 years in the Department of ENT of a peripheral tertiary care hospital wherein all subjects having a pure tone audiometry were included in the study. The records of PTA done were analyzed followed by systematic analysis. Results: A total of 9790 individuals inclusive of 5566 males and 4224 females were studied. Maximum no of individuals belonged to the age group of 21-30 years. Nearly 63% of total subjects suffered from Bilateral hearing loss. Sensorineural hearing loss was most prevalent type of loss. Mild degree of loss was most prevalent. Adolescents and young adults comprised the bulk of the study population. Sensorineural hearing is the most common type. Bilateral hearing loss is more frequent. Mild degree of loss is most frequent. Conclusion: This study emphasized the ‘Composite parameter distribution’ in addition to the classical single parameter demographic profile of deafness in a remote tertiary care hospital. Adolescents and young adults comprised the bulk of the study population. Sensorineural hearing is the most common type. Bilateral hearing loss is more frequent. Mild degree of loss is most frequent.
