Resonant frequency shifts induced by a large spherical object in an air-filled acoustic cavity
(J. Acoust. Soc. Am., 2007-06)
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 ...

Modified method of acoustic Rhinometry
(Taylor & Francis As, 2002-04-01)
Acoustic rhinometry is a well-known method for evaluating nasal cavity patency Using sound waves. the method produces graphical information on cross-sectional areas. the distances between these areas and the nostril and ...
Rhinometric evaluation of nasal cavity geometry and its relation to the upper arch transverse distance
(Sociedade Brasileira de Pesquisa Odontológica, 2009)
The objective of this study was to evaluate children's respiratory patterns in the mixed dentition, by means of acoustic rhinometry, and its relation to the upper arch width development. Fifty patients were examined, 25 ...
Acoustic signal associated with the bursting of a soap film which initially closes and overpressurized cavity Experiment and theory
(2005)
We report an experimental study of the sound produced by the bursting of a thin liquid film, which initially closes an overpressurized cylindrical cavity. There is a need for a deep understanding of the phenomenon, which ...

Análise teórica e experimental vibro-acústica utilizando a técnica de matrizes compactas
(Universidade Estadual Paulista (Unesp), 2008-12-22)
Em muitos problemas do nosso cotidiano ocorre acoplamento entre a resposta acústica no interior de uma cavidade e a excitação estrutural em um de seus contornos flexíveis, bem como a resposta estrutural nestes contornos ...
