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) ...

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 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 ...

In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it ...

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.

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 ...

Sound absorption Incoming acoustic waves induce relative movements among the fibres, initiating the triboelectric effect within overlapping regions. The generated charges are dissipated through ...

For applications where mounting acoustical wall treatments are impossible or undesirable, ProMAX Panels are lightweight, stand-mounted, portable StudioFoam sound absorbers. They are used in such ...

The research team from The University of Hong Kong presented their findings at the Phononics 2025: 7th International Conference on Phononic Crystals/Metamaterials, Phonon Transport, Topological ...
