Vijayakumar & Ahmmed 2025 implications for audiological traits in Misophonia

A 2025 study evaluating audiometric assessments found that while high-frequency thresholds were lower than low-frequency thresholds across all groups, only the misophonia with hyperacusis group showed a significantly steeper high-to-low slope in the right ear. SRTs did not differ between groups. ULLs were lower in DST groups, especially at 4 kHz, but did not correlate with daily life impact. Tinnitus was more common in DST groups and, in the no DST group, was linked to lower 4 kHz ULLs in the right ear. Past OME history showed no group differences. Overall, routine audiological measures could not reliably differentiate misophonia from hyperacusis. (Vijayakumar & Ahmmed, 2025)
