OBJECTIVE 1. To record pure tone audiometry in non-diabetic subjects. 2. To record pure tone audiometry in diabetic subjects. 3. To make a comparative study of the auditory acuity of type 2 diabetics and normoglycaemic subjects. To analyse the effect of glycaemic status (FBS, PPBS), glycaemic control (HbA1c) and duration of type 2 diabetes on auditory acuity. METHODS Type of study--Case Control study, Sample size-100, 50 patients attending diabetic OPD and 50 non-diabetic patients attending medical OPD for some other illness. Type 2 diabetic patients between the ages 35 and 55 years and who were non- hypertensive were included. After selecting appropriate samples for the study based on the inclusion and exclusion criteria, a detailed history was elicited and clinical examination done as per the clinical proforma. The necessary investigations were done as per the proforma. The auditory acuity of cases and controls were compared in relation to glycaemic status (FBS, PPBS), HbA1c and duration of DM and statistically analysed. KEYWORDS Type 2 Diabetes Mellitus, Sensorineural Hearing Loss, Glycaemic Status.
