They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.

The sound sensor that I bought — really a microphone and a tiny amplifier — cost $7. The sound sensor I bought. The wiring for my little prototype was super simple.

Researchers at Stanford University have developed a "quantum microphone" that's sensitive enough to measure the individual particles of sound known as "phonons." “We expect this device to allow ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...

A research team has developed a novel auditory technology that allows the recognition of human positions using only a single microphone. This technology facilitates sound-based interaction between ...
