چکیده    Background and aim: misophonia, characterized by a decreased tolerance for specific auditory stimuli, has been insufficiently explored within audiology. limited research has been conducted, and the auditory mechanisms involved in this disorder remain to be explored. hence, our study aimed to investigate the auditory efferent systems in individuals with misophonia. by focusing on this specific aspect, we aim to contribute to a better understanding of misophonia and shed light on the underlying auditory mechanisms involved in the condition. methods: a cross-sectional research was performed with students from mysore university to investigate misophonia. the severity of misophonia was evaluated using the revised amsterdam misophonia scale. the participants were divided into two groups based on their misophonia severity: mild (n=15) and moderate-severe (n=15). all participants underwent transient evoked otoacoustic emissions with contralateral suppression to assess the auditory function. the overall amplitude and frequency-specific amplitudes were analyzed and compared across the various groups. results: the analysis of variance results revealed no significant differences between the groups in global amplitude suppression and suppression of all frequencies. these findings imply that the medial-olivocochlear bundle efferent pathway is intact among individuals with misophonia. conclusion: our findings have concluded that the medial olivocochlear bundle appears intact among individuals with misophonia (p>0.05). however, it is essential to note that the generalizability of these findings may be limited due to the relatively small sample size used in our study. therefore, further research involving a more extensive and diverse population is needed to validate and generalize these conclusions.
