Resumen de The Sound Field Around a Tuning Fork and the Role of a Resonance Box

F.Bogcz Bogdan, Antoni T. Pedziwiatr

• 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:

  — Why is a bare tuning fork such a weak emitter of sound? — What is the role of the resonance box? — Where does energy connected with larger intensity of emitted acoustic waves come from?
