Scientists from ETH Zürich developed a circulator device that uses self-sustaining oscillations to propagate sound waves in ...

Atmospheric air is that medium by which by far the greater number of sound-waves are conveyed to our ear, since it is only exceptional that this happens through solid bodies which are in contact ...

A vibrating object A material for the sound wave to travel through, such as air (we call this a medium) Something to detect the sound e.g. your ear Sound can pass through: Solids e.g. sounds will ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND, SPEED OF SOUND. Compare: ACOUSTIC RADIATION. The levels of outdoor NOISE, whether they are intrusive or the normal ...

Sound waves propagating through the intracluster medium is one mechanism whereby the intracluster medium can be heated, as ...

Sound is basically pressure waves that are moving through some medium. So the sound that we usually hear is going through the air. And it's transmitted as what are called "longitudinal waves." ...

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