Re: experiment on roughness of complex tones

Hello Jennifer,


The NH (normal hearing) part of Fig. 5 of the first of the papers that you have mentioned [J. B. Tufts et al. (2005), "Perception of dissonance ...", JASA 118, 955-967] displays the complex-tone dissonance score versus the frequency ratio. That curve has an interesting difference from the 1909 complex-tone results of Kaestner [dashed curve in Fig. 2 of Plomp and Levelt (1965)] and also from the results of my own psycho-acoustic experiments [Fig. 6 of R.F. (2007), "Psycho-Acoustic Experiments ...", Canadian Acoustics, Vol. 35 No. 3, 38-45]: In your curve, the major (5:4) and minor (6:5) thirds do not yield high consonance peaks, whereas according to the other just mentioned curves they are the most consonant of all two-tones with frequency ratios from 1.0 to 2.0. Probable reason for the disagreement: You asked the subjects to judge "dissonance", whereas Kaestner and I asked in our complete paired comparisons "Which of the two two-tones is more pleasant (angenehm)?" In my above-mentioned 2007 paper, I have tried to explain the pleasantness of the thirds.

Hi Alex,

You might also be interested in the following work we did in the area of dissonance/roughness:
