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 ...
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 ...
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 ...
A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...
Counter-intuitively, we also blow on a fire (or use bellows) to make it burn better ... Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame ...
