| Abstract | dc.description.abstract | Acoustic resonances are modified when objects are introduced
into a chamber. The magnitude of these changes depends on the object position,
size, and shape, as well as on its acoustic properties. Here, an experimental
study concerning the resonant frequency shifts induced by a solid
spherical object in a quasi-one-dimensional air-filled acoustic cavity is reported.
It is shown that Leung’s theory does not account quantitatively for the
observations. A novel and simple approach is proposed, based on the wave
equation in a cavity of variable cross section. The results fit more accurately
the measured frequency shifts. | en |
