Individual loudness functions obtained from all nine listeners. The geometric mean of the string length is plotted on a log scale as a function of level. The filled circles show data for the binaural tones and the open circles show the data for the monaural tones. The vertical bars show one standard deviation of the log of the string lengths. The solid thin lines show third-order polynomials fitted to the monaural average data and the dashed lines show third-order polynomials fitted to the binaural average data. The thick lines show the ratio of string lengths obtained for equal-SPL monaural and binaural tones as estimated from the polynomials.
Average data from the individual listeners (L6 omitted). The third-order polynomials fitted to the data were normalized by dividing each length by the average string length for the SPL tone in the binaural condition. The vertical bars show one standard error of the log of the string length.
Comparison between the average loudnesses of the monaural 200-ms tones obtained in the present paper (open circles) and the average loudnesses of the 200-ms tones (filled circles) obtained in Epstein and Florentine (2005).
Comparison between binaural (dashed lines) and monaural (solid lines) loudness functions extracted in the present paper (thick lines) and the loudness functions derived from the model (thin lines) Whilby et al. (2006).
Summary of the individual data (gender, age, thresholds at , and results). represents the absolute value of the threshold difference between the two ears of each listener. The Bi/Mono ratio is the averaged difference between the binaural and monaural polynomial fits to the data; Monaural exponent and Binaural exponent show the values of the exponents of the fitted power functions for levels above SPL.
