Many asymmetric absorbers are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass ...

If you live near a busy street, this new breakthrough from Switzerland could offer some long-awaited relief. Researchers at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) ...

If you live in a noisy urban area, you're gonna love the sound of this. Researchers in Switzerland have developed a material that can dampen street noise while being four times thinner than ...

Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface. The researchers, which recently ...

Bats eat a lot of moths, which they locate in the dark via echolocation. According to new research, however, some moths have evolved sound-absorbing fur as a passive means of defence – and it could ...

Did you know that moth wings have excellent sound-absorption qualities? And it seems like they will now be used to further improve today's soundproofing technology. A moth is pictured in Jardin, ...

Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.

Hankook Tire & Technology has patented a tire with self-generation and sound absorption. The tire includes a wall structure, a sound absorber, and an electronic unit for improved sound absorption ...
