Further test of a model for loudness coding after adaptation.

The present study attempted to fit Weiler and Hood's (1977) quantitative model for loudness coding to an additional set of simultaneous dichotic loudness balance (SDLB) adaptation data. The error of prediction for test values 10 dB above adapting intensity for 12 normal-hearing listeners was -2.7 to -4.7 dB, an average of -3.5 dB. Since the error of prediction was so nearly constant (S.D. = +/- 737 dB), it seemed reasonable to attribute it do differences in procedural technique, and to conclude that the loudness model does account for coding in the adaptation results.
