Scientists at ETH Zurich have created a device that allows sound waves to ripple in one direction only.

The device is made up of a disk-shaped cavity with three equally-spaced ports that can each send or receive sound.

When sound enters from one of the ports, the waves become non-reciprocal and can only be heard at the other ports.

The scientists say their technique may inform the design of future communications technologies.
