Abstract Since the presence of tinnitus is not always associated with audiometric hearing loss, it has been hypothesized that hidden loss may act as a potential trigger for increased central gain along neural pathway leading to perception. In recent years, study improved discovery cochlear synaptopathy and several objective diagnostic markers. This investigated three markers peripheral in subjects tinnitus: extended high-frequency thresholds, auditory brainstem response, envelope following response. addition, speech intelligibility was measured functional outcome measurement loss. To account age-related participants were grouped according age, tinnitus, thresholds. Group comparisons conducted differentiate between age- tinnitus-related effects All revealed differences, whereas no differences observed non-tinnitus groups. However, older group showed performance on low-pass filtered noise tests compared group. These scores significantly correlated distress, indicated using questionnaires, could be related hyperacusis. Based our observations, does appear underlying cause tinnitus. The improvement speech-in-noise explained by enhanced temporal fine structure encoding or Therefore, we recommend future research takes into factors, explores low-frequency encoding, thoroughly assesses
