Re: Perception of sequential tones as simultaneous tones.

[Emilio Renard <renard_es@xxxxxxxxx>]

Thank you for your answer. I understand your
explanation, but I refer
to something more basic: to the perception of rapid
tones and physically not simultaneous as simultaneous.
Per exemple in the line of the researches of Rasch
about real simultaneity in poliphonic music (although
here the sounds are normally relatively larges and
then, intuitively, I think that it seem more normal
that they are perceived as simultaneous) or the
phenomenon of the aparent temporal continuity (here
there is sounds no simultaneous that are percived as
simultaneous), or perhaps (I still have that read the
paper) in the case of the "Pitch for non-simultaneous
succesive harmonics" (Hall & Peters, 1981 JASA, 69).
