Re: harmonic vs. inharmonic sounds (one last time)



Thanks

I think my question is ... Do "you" perceive and/or hear, rather than the third person neutral. Perhaps this is why I'm a composer and not a scientist, I'm more interested in "you" then 'the' "them".

Hello Kevin,

Yes, I think. If the mentioned sine-tones are soft, then 100 Hz is heard as a "cubic" difference tone, f = 2f_1 - f_2; example: f_1 = 200 Hz; f_2 = 300 Hz; f = 100 Hz. If the sine-tones are louder, 100 Hz is heard as a first-order difference tone, f = f_2 - f_1; example: f_1 = 200 Hz; f_2 = 300 Hz; f 100 Hz.

Therefore, we shouldn't think of your complex tone as containing a 100-Hz pure tone. It is just that they both have the same pitch.

On reconsideration, I would reframe the question something as:

When hearing the partials 200, 300, 400, 500, 600, 700, do you perceive the fundamental to be 100 Hz? Do you hear a 100 Hz component?
