Jet wave amplification in organ pipes
The Journal of the Acoustical Society of America, 1998The amplification factor of an air jet waving over the mouth is estimated from flow visualization of the smoked jet, where the velocity ranges from 7–33 m/s, the Reynolds number from 1000–5000, and the sounding frequency from 130–580 Hz. The jet length is 15.8 and 10.2 mm in two models, while the jet thickness is 2.2 mm in both.

Many musical instruments (such as the stringed or brass sections) are capable of being muted in order to change their harmonic structure or acoustic output. The present investigation is aimed at determining how well wind instruments can be muted by studying ways of muting an organ pipe. Three methods of muting were investigated: 1.
