A new paper published in the journal Physical Review Research provides experimental support for the hypothesis that hand ...

The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that underlies the sound made when you blow across the top of an empty bottle. Experiments using baby ...

The researchers compared the human data to that produced with simplified replicas, as well as theoretical projections of how air would move through a traditional resonator, called a Helmholtz ...

Abstract: The theory of the confocal resonator is extended to include the effect of unequal aperture size and unequal radii of curvature of the two reflectors. The latter is equivalent to a periodic ...
