To David Huron: David, your mini-story does not really answer the question because the P&L-data show 35 Hz as the frequency of maximum sensory dissonance versus 70 Hz as maximum roughness (Z&F), both in the region of 1000 Hz. This is stated independently from whatever critical bandwidth is adopted. Data for maximum sensory dissonance/roughness at lower regions show, in both studies, a similar ratio of 2. To John Herschy: The reference is Zwicker and Fastl, Psychoacoustics, Springer-Verlag, 1990. The formula for AM is not specified but on inspecting the figures that illustrate AM-tones, I assume that (1+B*sin(2*pi*g*t))*A*sin(2*pi*f*t) may have been used, where g is the modulation frequency and f the carrier .
