Subject: Re: experiment on roughness of complex tones From: "reinifrosch@xxxxxxxx" <reinifrosch@xxxxxxxx> Date: Tue, 18 May 2010 15:45:12 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>------=_Part_3393_25613599.1274197512346 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello Jennifer, =20 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 fr= equency ratio. That curve has an interesting difference from the 1909 compl= ex-tone results of Kaestner [dashed curve in Fig. 2 of Plomp and Levelt (19= 65)] and also from the results of my own psycho-acoustic experiments [Fig. = 6 of R.F. (2007), "Psycho-Acoustic Experiments ...", Canadian Acoustics, Vo= l. 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 men= tioned curves they are the most consonant of all two-tones with frequency r= atios 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 complet= e paired comparisons "Which of the two two-tones is more pleasant (angenehm= )?" In my above-mentioned 2007 paper, I have tried to explain the pleasantn= ess of the thirds. =20 Reinhart. =20 ----Urspr=C3=BCngliche Nachricht---- Von: jennifer.tufts@xxxxxxxx Datum: 08.05.2010 17:57 An: <AUDITORY@xxxxxxxx> Betreff: Re: experiment on roughness of complex tones Hi Alex, You might also be interested in the following work we did in the area of di= ssonance/roughness: Tufts, J.B., Molis, M.R., & Leek, M.R.
