After the thread "Hidden slot" another question has come to mind:
We have learned that the mouthpiece end is the open end,
and from the laws of standing waves in a tube this should
mean that the wave pressure is low in a mouthpiece, since
the wave pressure is low in an open end. (unless I´ve
misunderstood, of course!).
Some people, who usually know what they talk about, say
otherwise, so my question is:
* is wave pressure low as I expect in the mp end?
* if not, then why not?
The part of the mp that I´m thinking of is the part immidiately
in front of the lips. The fact that the pressure will vary with
the size of the cross-section is not what I´m after. Instead
I´m just asking whether the mp follows the same laws as any
open end would do regarding pressure maxima/minima.
