I’d like to calculate the $Q$-factor for an acoustically resonating object. I’d like to keep the tests to a minimal, none if possible. Is there any way to do this?

  • $\begingroup$ You are going to have to provide more information, for example what kind of resonating object? A tuning fork? A tube with a standing sound wave inside? What kind of set-up do you visualize $\endgroup$ – Triatticus Mar 12 at 19:36
  • $\begingroup$ @Triatticus I’m trying to compare the resonance strength of a tube and a box when sound waves are affecting them $\endgroup$ – Melvin Mar 12 at 19:41

Measure the decay time. The number of oscillations for the amplitude to decay to $1/e =37$ % gives you the Q-factor.
