Air Columns And Toneholes- Principles For Wind Instrument Design ((new)) [Mobile]

(like a clarinet mouthpiece), air cannot move, creating a displacement node (and a pressure antinode). Bore Shape and Harmonics Cylindrical (Open-Open)

The arrangement of toneholes along the bore forms a , which behaves as an acoustic filter with a characteristic cutoff frequency . Below the cutoff frequency, the lattice acts as a stop-band: low-frequency waves are reflected by the first open hole, which provides an acoustic "short circuit" to the outside air, fixing the pressure at atmospheric and creating a pressure node. (like a clarinet mouthpiece), air cannot move, creating

In reality, the air column does not stop abruptly at the first open tonehole. A portion of the acoustic wave leaks past the first open hole and interacts with the subsequent open holes down the line. This series of open holes is known as an . In reality, the air column does not stop
