Sound shield: An acoustic cloak comprising alternating layers of sound-scattering materials should make objects invisible to sonar–and insulated from sound. In this computer-generated image, a ...

Engineers created a low-cost, AI-powered drone detector that listens for engine noise. Is acoustic monitoring the future of security?

What if you could put a shield around your city to prevent it from being demolished in an earthquake? A group of French scientists think they've created a way to do just that, thanks to refraction ...

Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the ...

City dwellers, rest easy. Engineers have designed a material that redirects sounds and could be used in buildings to shield them from noises. The sound-shielding material, which, if actually made, ...
