I have read your work so far on horn theory Martin. Excellent work , i really mean it.I have been fighting with the math and you have expressed it in a much cleaner way.A lot of it i am still grappling with.First, I have to finish the room boundary impact on mouth impedance and size
While doing several waveform sims i happened to notice that room volume had an almost resistance activity to the wave as it was exiting?Makes sense on a physical level.

Again Martin, excellent work
