Researchers have created a new sound wave director that can target specific ports and mute sound everywhere else.

A team of researchers has found a way to make sound waves propagate in one direction only, which could help avoid unwanted reflections and possibly pave the way for the same to be done with ...

After years of research, scientists at ETH Zurich have developed a method to make sound waves travel in a single direction.

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. Water, ...

When placed against the mouthpiece of the instrument the air inside begins to vibrate too, forming sound waves. To make different notes the amount of air vibrating inside the instrument has to be ...

We can't hear these sound waves, but when they reflect off different parts of the body, they create echoes that are picked up by the probe and turned into an image called an ultrasound scan.
