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 ...

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 ...

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. Experts at the University of Bristol have ...

Heavy curtains made from thick material such as velvet are often needed to keep noise out of indoor environments, but Swiss researchers have come up with another option. The Empa researchers, in ...

Absorbing low frequency sound is a big job, or at least, a job for big things. Acoustic absorption systems require big resonant cavities with large amounts of heavy damping material and significant ...

Haley Mast is a freelance writer, fact-checker, and small organic farmer in the Columbia River Gorge. She enjoys gardening, reporting on environmental topics, and spending her time outside ...

"Acoustics" in architecture means improving sound in environments. Although it is a complex science, understanding the basics - and making efficient and effective decisions - is much easier than you ...

Nov. 6 (UPI) --The fur on the thorax of some moths absorbs the sound waves emitted by bats and their sonar systems, making them harder to detect, according to new research by scientists at Bristol ...
