# Is there a way to calculate the $Q$-factor?

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?

• 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 – Triatticus Mar 12 at 19:36
• @Triatticus I’m trying to compare the resonance strength of a tube and a box when sound waves are affecting them – 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.
