Artist’s impression of an array of nanomechanical resonators designed to generate and trap sound particles, or phonons. The mechanical motions of the trapped phonons are sensed by a qubit detector, which shifts its frequency depending on the number of phonons in a resonator. Different phonon numbers are visible as distinct peaks in the qubit spectrum, which are shown schematically behind the resonators. (Image credit: Wentao Jiang)

Counting sound particles with quantum microphone

Now it is possible to measure individual particles of sound, called phonons- thanks to Stanford Scientists who developed quantum microphone. The quantum microphone is...

How our brain distinguishes between voice and sound?

Researchers at UNIGE and Maastricht University have demonstrated that the brain adapts to a person’s listening intentions by focusing either on a speaker’s voice or on the speech sounds that are being uttered.
Boston University mechanical engineers have created synthetic, sound-silencing structures—acoustic metamaterials—that can block 94% of sounds.
