Physicists split bits of sound using quantum mechanics - Science News
Jun 16, 2023 · Sound waves (illustrated) come in tiny quantum chunks called phonons. New experiments show how phonons exhibit the same quantum weirdness shared by photons and subatomic particles.
Fundamental constants place a new speed limit on sound - Science News
Oct 9, 2020 · Physicists propose that sound waves can't go faster than 36 kilometers per second under normal conditions on Earth, based on fundamental constants. The speed limit depends on the fine-structure...
Physicists discovered special transverse sound wave
Dec 7, 2021 · A research team at City University of Hong Kong discovered a new type of sound wave that vibrates transversely and carries both spin and orbital angular momentum like light does. They used a...
Physicists Generated Sound Waves That Travel in One Direction …
4 days ago · There are times when it would be useful to make sound non-reciprocal, perhaps when noise suppression is required. In 2014, researchers at the University of Texas at Austin developed an acoustic circulator, which used small fans to blow air through a resonant ring.When sound enters from one of three ports, the sound waves become non-reciprocal and can only be heard at one of the other ports ...
