Acoustics is the branch of science that studies the propagation of sound and vibrational waves. Audible acoustic waves are ubiquitous in our everyday experience: they form the basis of verbal human ...

With the involvement of scientists from the Paul Drude Institute for Solid State Electronics in Berlin and the Universities of Augsburg and Münster, international researchers have presented a new ...

Look at that mountain! Imagine you are standing at the base of a volcano looking up. You were told that the volcano isn’t going to erupt anytime soon, but you notice a little bit of smoke (or is that ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...

This article was originally published on The Conversation. Read the original article. We know that there is sound on planets and moons in the solar system—places where there's a medium through which ...

Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

This morning, scientists from the Laser Interferometer Gravity Observatory announced that LIGO had detected gravitational waves from the collision of two black holes, an event so cataclysmic that it ...
