I just caught this post on arXiv: “A Lip Vibration Model Using Mechanical Properties of Flesh”. #MusicalAcoustics
A Lip Vibration Model Using Mechanical Properties of Flesh
The mechanical properties of the human lip between relaxed and fully contracted are not enough to explain the full range of professional brass players. Brass players manipulate their mouth cavity and vocal tract which act as Helmholtz resonators driving the lips. Brass players increase their upper ranges by reducing the amount of lip mass that vibrates using upstream or downstream techniques. In addition, it was found that the cup of the mouthpiece is a separate resonating cavity: not just an extension of the instrument funneling air down the length of tube. For the lowest three octaves of the range, the trombone does not act as a tube with a standing wave resonance, but as a transmission line responding to a string of pulses produced by the lips.
When I saw this headline, I thought “tuned mass damper” and hoped it would be a great lesson in physics and/or #acoustics. I was not disappointed. #iteachphysics and engineering educators should take note! https://wapo.st/4aq40lp
Today I’m thankful for the Instagram algorithm that has decided to show me tons of college volleyball posts. (That, and my family.)
