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 ...

Acoustics is the branch of science that studies the propagation of sound and vibrational waves. Audible acoustic waves are ubiquitous in our everyday experience: they form the basis of verbal human ...

Your speakers are the most important part of your audio setup, but do you know how they're able to playback multiple sounds ...

In A Nutshell Researchers used focused sound waves to temporarily quiet the amygdala in healthy adults, reaching a deep brain ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...
