Hand clapping is ubiquitous behavior for humans across time and cultures, serving many different purposes: to signify approval with applause, for instance, or to keep time to music. Acousticians often ...

A fifth-grader has written this blog asking for help with a science project... does anyone have any theories on the sound level (dB) and frequency (Hertz) of the average hand clap? I think he's trying ...

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 ...

Clapping is both a scientific event and a social gesture. A study explores the complex physics behind the sound of clapping. The noise originates from compressed air, not just hand collisions.

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 ...

The clapping hands emoji: When used repetitively in a row, it signifies applause, but as any social media user by now understands, that is not the emoji's primary placement in the world of Twitter.
