The design halves the width of material needed to absorb low-frequency noise, making it practical for real-world applications ...

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 ...

Scientists show that a thin layer of plasma, created by ionizing air, could be promising as an active sound absorber, with applications in noise control and room acoustics. Did you know that wires can ...

Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it’s possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, ...

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 ...

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 ...

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 ...

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) ...
