Hello!
On vocalization I have nothing to say -- but this discussion has made me think of a question related to the mechanics of the mammalian cochlea: In the basal half of the cochleae of chinchilla, guinea-pig, and gerbil, during a sine-tone of (high) frequency f the "characteristic place" (place of maximal excitation at low sound-pressure level) has been found to be basal of the without-liquid resonance place of the basilar membrane [where sqrt(S/M) = 2pi*f; S = effective BM stiffness, M = effective BM mass surface density] by about 0.5 one-octave distance. Are there new results on the distance between those two places in homo?
