Baluncore replied to the thread Valsalva and Eustachian tube.No. In some cases, when the ET contains a fluid, the fluid can move sufficiently to equilibrate pressure, without completely emptying... -
Baluncore replied to the thread Undergrad Measured Spectrum of Stopped Wood Organ Pipe Shows ALL Overtones.The third harmonic, at 3f, is the perfect fifth, in the octave above the fundamental. If you refer 3f to the octave it falls in, then...
