Abstrakt: It has been found that loudness judgments adapt to monaural stimulus increments [E. M. Weiler, D. E. Sandman, and L. M. Pederson, Brit. J. Audiol. 15, 201-204 (1981)]. The present study was undertaken to determine whether the changes in high-frequency recruiting ears measured at a nonrecruiting frequency (1000 Hz), were the same as in normal listeners. Both groups showed a similar decline in judgment to the baseline 660-dB tone. There was a significant interaction between groups, intensity, pulsed duration of an interspersed 10-dB increment, and successive judgments of loudness. Similar interactions were seen at 20 dB above the baseline intensity. [ABSTRACT FROM AUTHOR]
