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 ...

The researchers used high-speed cameras to track the hand motion, air flow and sound of 10 volunteers clapping, measuring the ...

Clapping faster produces a louder initial sound, while lower skin elasticity produces a longer-lasting sound. In short, "Our work provided the first experimental support for the theoretical ...

The researchers used high-speed cameras to track the hand motion, air flow and sound of 10 volunteers clapping, measuring the different frequencies when the size and shape of the cavity between ...
