Imagine a world where you can effectively block sound without the need for bulky and sometimes costly insulation. A game-changing technology is making this possible – a unique material that can block ...

There may be new hope for people with noisy neighbors. Scientists at MIT have developed a method of using thin sheets of fabric to either cancel or block sound – in the latter case, the racket even ...

Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. Rotons are an exception: their speed of sound changes significantly with the wavelength, it is also ...

Researchers have succeeded in controllably propagating sound waves along the boundaries of topological metamaterials using a modulation technique that breaks time-reversal symmetry. This feat, which ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Acoustical comfort is a critical element of interior design that should never be neglected, especially in shared spaces such as restaurants, convention centers, museums, sports halls, and many others.

Scientists experimenting with a cutting-edge ultrasound technique have come up with a groundbreaking and incredibly precise way to measure the elasticity of materials at a microscopic scale. Based on ...

The brilliant metallic blue wings of Morpho butterflies dazzle the eye. Branched nanostructures on the wings scatter light in complex ways to produce this characteristic iridescent hue. By harnessing ...
