Posterior medial Heschl’s gyrus activation best predicts individual perceived loudness

Evidence

Although it is yet to prove how well the present findings pertain to the hearing impaired listeners, our results so far point towards the activation of the posterior medial section of Heschl’s gyrus as the most reliable indicator of individually perceived loudness. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2610

A promising next step would be the inclusion of hearing impaired participants characterized by an altered relationship between sound intensity and perceived loudness (e.g., loudness recruitment). Moreover, this approach could provide additional valuable information about the nature of hearing disorders associated with distorted loudness perceptions. This in the end might open a potential for the diagnostic use of auditory fMRI. Although it is yet to prove how well the present findings pertain to the hearing impaired listeners, our results so far point towards the activation of the posterior medial section of Heschl’s gyrus as the most reliable indicator of individually perceived loudness. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2647
