Using an online tone generator I can hear and feel sound down to under 20hz in my listening area, how coherent that is is another matter. But looking at sound generation, no driver moves anywhere near the distances you describe in generating that, so I think you mean distance time delay, and not pressure level peaks. After all, a grand piano’s low A string is less than 8’ long, and to create that tone only requires it to travel a fraction of an inch.
As far as upper limits I will only consider third level harmonics, as that is what the 20khz is for, not actual notes while the energy above that is measurable, most of us cannot hear it, although I think many of us listen with our sense of touch as well, so I'm sure we can feel it.
To @everyoneelse;
It would seem treble is fair game as well. And I am interested in all aspects of musical sound generation/reproduction so to use an upright bass as an example, I want to hear the musicians fingers sliding up and down the strings while playing it; which can go very high up the frequency range, as well as the woods resonance in an acoustic version, and the lower harmonics that accompany the center of the note.
I guess I was assuming that we would be talking about sitting in your room listening measurements/experience and not a speaker in vitro, so no Anechoic chambers allowed.
I just wonder what people find acceptable, since I know many people have very expensive, to me, systems that can barely manage 40hz, -0db down.
Unfortunately Vandertones is an .exe, and so not available for the Mac. As I’ve mentioned, I use an online signal generation site. But have bought a decent portable recorder, and am now looking for opportunities to record pure notes of individual instruments, and I have a friend who is the department head in choral studies at a local university, so am going to see if I can wrangle some time in their concert hall to record the piano, which is already there.
That will be an interesting database to make available to all who might want to add to, or use the file from. Perhaps there is already a start out there?
