For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. For the first time, scientists have shown that ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Scientists from CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to ...

To understand why there’s no sound in space, first consider how sound works. Sound is a wave of energy that moves through a solid, a liquid or a gas. Sound is a compression wave .

Sound waves can reflect off surfaces. We hear reflected sound as an echo. Hard, smooth surfaces are particularly good at reflecting sound. This is why large, empty rooms produce lots of echoes.

Sound—in the form of shock waves—helps sculpt the beautiful, delicate structures of some supernova remnants, such as those seen here in a Hubble Space Telescope image of the Veil Nebula.

They then played 1,590Hz sound waves from the speaker array to glide the ball through a pre-planned path while microphones detected feedback known as a scattering matrix as it bounced off the ball.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we ...
