Air Columns and Toneholes: Principles for Wind Instrument Design**
where \(f_n\) is the resonant frequency, \(n\) is an integer, \(c\) is the speed of sound, and \(L\) is the length of the air column. Air Columns and Toneholes: Principles for Wind Instrument
The behavior of air columns and toneholes can be modeled using mathematical equations, such as: \(n\) is an integer
where \(Z\) is the acoustic impedance, \( ho\) is the air density, \(c\) is the speed of sound, and \(A\) is the cross-sectional area of the tonehole. \(c\) is the speed of sound
Similarly, the acoustic impedance of a tonehole can be modeled using:
\[f_n = rac{n ot c}{2 ot L}\]
