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

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

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.
