So, researchers developed a method to make sound waves travel in only one direction. The innovation has far-reaching applications that go beyond acoustics, such as radar. After years of research ...
In that paper, they discuss how they improved upon the original design to create a sound wave director that doesn’t cause the waves to lose energy as they travel. They also hope that this new ...
To return to the analogy from earlier, two people in a room conversing at the same volume with no obstacles between them can hear each other clearly as the sound waves move freely in both directions.
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 ...
