Hearing-impaired listeners show faster loudness growth but similar discomfort thresholds

Evidence

Loudness is a perceptual quantity that, although correlated with stimulus intensity, is also influenced by other acoustic factors such as frequency and stimulus bandwidth. Loudness is measured using techniques based on rating and matching, and these different techniques can be used to make inferences about the growth of loudness with increasing intensity (rating experiments) and the influence of frequency on loudness (matching experience). In comparison to listeners with normal hearing, listeners with hearing loss experience a more rapid growth of loudness with increasing intensity but do not generally experience different loudness discomfort levels. As rating and matching experiments adopt methods that yield variable and sometimes biased results, intensity-discrimination experiments are also commonly used to assess the representation of intensity in the auditory system. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 865
