The Sound Field around a Tuning Fork and the Role of a Resonance Box
Bogacz, Bogdan F.; Pedziwiatr, Antoni T.
Physics Teacher, v53 n2 p97-100 Feb 2015
Atypical two-tine tuning fork is barely audible when held vibrating at an arm's length. It is enough, however, to touch its base to a table or, better, to a resonance box and the emitted sound becomes much louder. An inquiring student may pose questions: (1) Why is a bare tuning fork such a weak emitter of sound? (2) What is the role of the resonance box? and (3) Where does energy connected with larger intensity of emitted acoustic waves come from?
