Data gathered by Korman and Weiler [MA thesis, Univ. of Cincinnati, 1986] and Janson etal. [Br. J. Audiol. 30, 35–42 (1996)] have shown the loudness function for loudness adaptation gathered by the ipsilateral comparison procedure (ICP) differs for normal hearing listeners and those with high‐frequency cochlear loss. This paper investigates the modeling assumptions for loudness growth in the two kinds of listeners. Surprisingly, the loudness growth within a given frequency is not clearly different in kind, although the two groups start with different values in most test conditions. However, there does appear to be a difference across frequencies which may be a reflection of the spread of excitation on the basilar membrane. Expected differences in activation for normal listeners and those with a high‐frequency loss will be discussed. |
