A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that ...

In a scene toward the end of the 2006 film, "X-Men: The Last Stand," a character claps and sends a shock wave that knocks out ...

Researchers elucidate the complex physical mechanisms and fluid dynamics involved in a handclap, with potential applications in bioacoustics and personal identification, whereby a handclap could be ...

Scientists have finally unravelled the complex process that generates sound during handclaps, a discovery that shows how even simple acts can be rich with physics. The research, published in the ...
