A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Hey all! So all my life I have heard that sound is a type of wave. This seemed to make sense to me. Recently I have come across some information that has me second guessing such tradition knowledge.

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...

Wave sounds pro 2.0 Review;The advantages of wireless headsets continue to attract consumers’ attention. The most obvious difference between the two types is the biggest benefit of wireless headphones ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

This array of piezoelectric sensors is designed to install in theaters and concert halls to harness sound wave energy to create electricity. This miniature proof of concept included 1,042 sensors, and ...
