Question

in general when an air chamber gets smaller its resonant frequency goes___ up or down?

Answer 1

f resonance =. (sound speed /2*pi )*sqr(A/(V*L).

A area of cross section , L is length of tube , V is volume .

F resonance =n*v/4*L where is n is number of overtone

n is natural number

So decrease in L mean increase. In resonance. Frequency
