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

The “Helmholtz resonator” concept explains the frequencies of sound produced by clapping the hands together in different configurations.

Researchers at Osaka University have revealed a link between the equations describing strain caused by atomic dislocations in ...

The research confirms that the Helmholtz resonator model can predict handclap frequencies, highlighting the role of soft tissue in sound attenuation. This understanding could enable personal ...

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 ...
