Chen Shen, assistant professor of mechanical engineering at Rowan University, uses acoustic science to spin and manipulate sound waves for micro applications including miniature robotics and new ...

Futuristic control of structure in some materials is being made possible by a physics loophole.

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 ...

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 ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

The sensation felt by our ears is called sound. It is a form of energy which makes us hear. We hear several sounds around us in our everyday life. We know that sound travels in the form of wave. A ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

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 ...
