harmonic vs. inharmonic sounds (again one last time)
Sorry for my poor email etiquette.
Before moving on to a more central interest, I will extend this with
an another idea.
I play the 200, 300, 400 etc collection and listen carefully.
I play the 100, 200, 300, 400 etc collection and listen carefully.
I turn off the stimulus and in my head I "re-listen" [*] to the two
My question: what would be a 'better' word to more accurately
describe the [*] re-listen used above.
Am I now "thinking" the 'sounds'; thinking 'about' the sounds?
When someone speaks to me, I almost immediately replay what they are
saying picking out the key aspects / features creating a hierarchy of
dealing with ideas which are to be handled in a quasi-sequential
fashion, although, as for example in here, presented in a non-closely
sequential fashion, along with interruptions and elaborations.
Or is this what is partially meant by 'cognition'?

Your latest posting to the list contains the first of my private
messages on difference tones, but not the second message which was a
correction of the first one. Anyhow -- here is what I personally
If I play on a synthesizer simultaneously two sine-tones of
frequencies f_1 and f_2, softly at first and then with continually
increasing volume, I hear difference tones if the ratio f_2 / f_1 is
in the range from about 1.2 to 1.4.
For example, for f_1 =3D 400 Hz and f_2 =3D 500 Hz, I hear, at very low=20
volume, no difference tone. Then, at slightly higher volume, I hear a=20
cubic difference tone, f =3D 2f_1 - f_2 =3D 300 Hz. At still higher=20
volume, I hear a first-order difference tone, f =3D f_2 - f_1 =3D 100=20
See, e.g., R. Plomp, "Detectability Threshold for Combination
Tones", JASA 37 (1965) 1110-1123.

I think my question is ... Do "you" perceive and/or hear, rather=20
than the third person neutral. Perhaps this is why I'm a composer and=20
not a scientist, I'm more interested in "you" then 'the' "them".
