THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

IT has been well established by several investigators 1,2 that, in the case of diffraction of light by ultrasonic waves, the first orders of diffraction on either side of the central zero order appear ...

This is a very popular video on the internet right now. It shows this awesome set up that uses sound to levitate very low density and small objects. I think this is a great opportunity to talk about ...

Researchers have developed a way to use sound to create cellular scaffolding for tissue engineering, a unique approach that could help overcome one of regenerative medicine’s significant obstacles.

In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...
