The global low frequency sound absorbing insulation material market was valued at USD 160.7 million in 2023 and is ...

If you live in a noisy urban area, you're gonna love the sound of this. Researchers in Switzerland have developed a material ...

That’s why Empa researchers teamed up with de Cavis to develop ultra-thin sound absorbers made from gypsum or cement foams.

The plasma absorber is also more compact that most conventional solutions. Exploiting the unique physics of plasmacoustic metalayers, the scientists experimentally demonstrate perfect sound ...

From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic ...

Empa researchers have developed innovative sound absorbers made of mineral foams. Not only are they significantly thinner than conventional ...

Moth wings as sound absorber metasurface. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022; 478 (2262) DOI: 10.1098/rspa.2022.0046 ...
