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

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.

A new tool that assesses the level of danger posed by tsunamis in real-time has been made operational on a global scale.

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

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 ...

The SONU Band uses personalized sound therapy—not steroids—to redefine allergy relief. Inside the startup behind SONU, the AI ...

In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave — including halting fat development.

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—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.

The process used to direct the sound waves not only guides the waves in one direction but the researchers say it also amplifies them. From ETH Zurich: “Schematics of the experimental set-up ...

Scientists managed to significantly boost the production of green hydrogen using sound waves in a clean energy breakthrough. The "exciting" study combined high-frequency sound waves with less ...
