[QUOTE="abadcliche, post: 226402, member: 4455"] So will the magnahelic measure both suction and pressure? That's what a pad experiences in real usage, so I'd think that would be a good way to go. Also the setup looks super cool, but perhaps the acrylic sheath should be moved out of the way so that the fringes of the "tonehole" are unencumbered like they would be on a real saxophone. How do the pressures of a magnahelic compare the the pressures of a wave passing by inside a saxophone bore that is actually being played? Do we know what maximal pressure is? At least enough to blow a low Eb open for some people. I'd wager that's fairly high, and the equivalent of suction when the low pressure part of the wave passes by. If ANY air leaks in- or out- during playing, well you've brought the peak and the trough of the wave closer together, decreasing amplitude, which is a to say turning down the volume. It would be interesting to do the same experiment with a tiny leak, like perhaps you could lay a grain of sand or a beard hair on the tonehole rim. [/QUOTE]
