An ‘acoustic prism’ can split sound the way a regular prism splits light

An ‘acoustic prism’ can split sound the way a regular prism splits light Here’s a new invention that, while potentially useful, is even more interesting as an illustration of the nature of sound: the acoustic prism.Now, researchers have created a similar device for sound, which passively and naturally splits sounds into their component frequencies.

Researchers discover how to shape sound in 3D

Researchers discover how to shape sound in 3D Manipulating waves in 3D requires a phased array of transducers, but phased arrays are limited in spatial resolution by the physical size of each transducer.Now a team of researchers from the Max Planck Institute in Stuttgart, Germany have figured out an inexpensive way to shape sound waves in 3-space, using 3D printing.
