Listeners with identical hearing thresholds differ in suprathreshold loudness perception
Evidence
Loudness is a suprathreshold percept that provides insight into the status of the entire auditory pathway. Individuals with matched thresholds can show individual variability in their loudness perception that is currently not well understood. As a means to analyze and model listener variability, we introduce the multi-category psychometric function (MCPF), a novel representation for categorical data that fully describes the probabilistic relationship between stimulus level and categorical-loudness perception. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2509
