Hearing is one of the most complex functions among human beings. Deficits in the ability to hear become noticeable to an individual only after the impairment reaches moderate to severe degree. Advances in the field of Audiology are still developing in the country and yet to reach the corners of the country in form of hearing screening program. Many research studies happening in India and globally, enquire about the hearing status of the participants, since hearing loss can be a strong variable. Even though these studies rely on the self-reported details of the participant about his hearing status, there is dearth of data to support the validity of such self-reports. The aim of the study was to investigate the association between self-reported hearing problems and the results of the audiometric measurements among the adults who came to the Audiology OPD. Study followed a cross sectional research design where 1036 adults (599 males & 437 females) between the age ranges of 17-85 years were enquired about their awareness towards the presence of hearing loss in them. Responses were obtained in a closed set of Yes/No. The report of hearing loss was correlated with the pure tone average values obtained for the subjects for various frequency zones and their speech identification scores. Results revealed a strong correlation between the low frequency pure tone average values and the self-report. Study confirmed the clinical observation of high frequency loss of milder severity going mostly unnoticed. A fair correlation was observed for the speech identification scores which has been discussed in relation to the type of loss and the suprathreshold speech perception ability.
