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

Sound activated switches are nothing new, but the way The Clapper did it was just slightly brilliant. Instead of listening to every sound, the mic inside the magic box sends everything through a ...

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

We wanted to explore how we generate the sound depending on how we clap our hands." The researchers used high-speed cameras to track the hand motion, air flow and sound of 10 volunteers clapping ...

You stand a long distance from a wall, clap, and listen for the echo. The distance travelled is twice the distance from you to the wall (because the sound has to travel to the wall and back).

After all, who needs home automation when you can clap on and clap off ... We were trying to think of how you could make a sound-sensitive element out of common parts. After all, you don ...
