A quieter world through materials by design

Posted on by

A new paper published in Applied Physics Letters co-authored by Prof. Osama Bilal and his PhD student introduces materials that can simultaneously block sound and vibrations at tunable frequencies by design.

Concept: (a) Auxetic vibro-acoustic metamaterial can attenuate both elastic and acoustic waves. (b) By applying an external load to the metamaterial, we can tune the attenuation frequency range for both airborne sound and mechanical vibrations, in all directions. Image courtesy of Prof. Bilal.
