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 ...

Any discussion of what happens when an object breaks the sound barrier must begin with the physical description of sound as a wave with a finite propagation speed. Anyone who has heard an echo (sound ...

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 ...

The area of sound is fascinating researchers and after a recent study of bendable sound waves that could result in localised reception, they have now delved into how sound can be used in weight loss.

Introduction Did you know that not all animals use their ears to hear sounds? Snakes, for example, perceive sound waves through their jawbones! And many insects perceive sound waves through their ...
