Objectives: The purpose of this study was to examine the relationship between noise exposure history, type 1 diabetes mellitus (DM), and suprathreshold measures of auditory function. Design: A cross-sectional study was conducted; 20 normal-hearing participants without type 1 DM were matched on age and sex to 20 normal-hearing participants with type 1 DM (n=40). Participants, all having normal audiometric thresholds, completed noise history questionnaires and a battery of auditory physiological tests including transient evoked otoacoustic emissions, distortion product otoacoustic emissions, and auditory brainstem responses (ABR) at 80 dB nHL and at 2 different stimulus rates in both ears. Amplitude and latency for waves I and V are presented. Statistical analysis included analysis of variance and multivariate linear regression. Results: No statistically significant difference for noise exposure history, otoacoustic emissions (OAE), or ABR findings were found between type 1 DM and matched controls. Males and females showed statistically significant differences for OAE amplitudes and ABR amplitude and latencies. However, no statistically significant relationship was found between noise outcomes and OAE or ABR findings. Conclusions: No statistically significant relationship between noise history and our suprathreshold ABR or OAE findings was indicated for individuals with type 1 DM or matched controls. The lack of evidence of noise related neuropathology might be due to inadequate noise exposure or lack of comorbidities in our DM group. Implications of these findings are discussed.
