In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

A study on the levitation technique titled "High-speed acoustic holography with arbitrary scattering objects" has been published in the journal Science Advances. Researchers from the University ...

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 ...
