New architecture could be used to create tailored devices that emit or receive only certain frequencies of sound ...

The power of sound reaches far beyond your ears. While you're used to hearing sound through music, voices, or noise, your body is also quietly listening—at the cellular level. Recent research shows ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it.

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of ...

The measurement enables them to predict the speed of sound in neutron stars, which are also thought to comprise strongly interacting Fermi gas, albeit with 25 orders of magnitude higher density.
