Online published on 23 December, 2019. Abstract Introduction The literature provides a clear evidence of involvement of auditory system from peripheral auditory system to auditory cortex in individuals with Type-II diabetes. Speech perception in noise, along with auditory brain stem responses (ABR) and otoacoustic emissions have been found to be affected in these individuals. The speech perception ability is affected in these individuals which can be associated with central auditory processing ability. There is a need to understand central processing ability involvement. Hence aim of the present study was to explore the effect of Type-II diabetes on temporal processing abilities like modulation detection and gap detection thresholds. Method The research was carried out on 40 participants, between the age ranges of 28–60 years, who were diagnosed as having Type-II diabetes since 5 years and compared to control age and gender matched participants without diabetes. Results Independent t-test was applied to assess the statistical significance between both the groups. The results reveal that the group of participants without diabetes performed better than the group of participants with type-II diabetes. Conclusions There is an involvement of central auditory processing ability on task of modulation detection and gap detection in participants with type-II diabetes.
