The neural site where intensity becomes loudness remains unknown.

Evidence

The current literature still does not provide definite answers to the following questions: (1) At what stage or stages along the auditory pathway is sound intensity transformed into its perceptual correlate (i.e. loudness)? (2) What are the functional differences across regions within AC with respect to loudness-related activation? Promoting a better understanding of the neural basis of loudness might, in the long run, improve diagnostics and treatment of hearing disorders characterized by a distorted loudness perception, e.g. loudness recruitment. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2612

Categorization

• QUESTION: The two open questions — where intensity-to-loudness conversion happens and how AC subregions differ — are precisely what this study aims to answer.
• corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 2612; Dijk, Pim van, Physiology, Psychoacoustics and…, 2610
