Background: The present study was conducted for comparing the hearing threshold levels among adult diabetes mellitus patients in a known region.Materials &Methods:A total of 200 subjects with presence of type 2 diabetes mellitus were enrolled. Complete demographic and clinical details of all the patients were obtained. All the subjects were evaluated for pure tone average (PTA), speech discrimination score (SDS), and speech reception threshold (SRT) tests.The patient's blood pressure was checked. Blood samples were obtained and renal profile was evaluated. In addition, a physical examination of both ears was performed using an otoscope. Patients underwent audiometric testing using the PTA, SDS, and SRT tests. All the results were recorded in Microsoft excel sheet followed by statistical analysis using SPSS software.Results:Significant results were obtained while comparing the hearing threshold among subjects of diabetic group and control group. Normal PTA findings were seen in 51 percent of the patients of the diabetic group and in 98 percent of the patients of the control group. On comparing the PTA findings among diabetic group and control group, significant results were obtained.While comparing the hearing thresholds at different frequencies among diabetic group and control group, significant results were obtained. Conclusion:Patients with diabetes have a significant prevalence of hearing loss, primarily sensorineural hearing loss.
