Individual loudness perception can be assessed using categorical loudness scaling (CLS).
The procedure does not require any training and is frequently used in clinics. The goal of
this study was to investigate different methods of loudness-function estimation from CLS
data in terms of their test–retest behaviour and to suggest an improved method compared to
Brand and Hohmann (2002) for adaptive CLS. Four different runs of the CLS procedure
were conducted using 13 normal-hearing and 11 hearing-impaired listeners. The following …
