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 ...

Looking for attractive wallpaper that cuts down the noise? Sound reducing technology has come a long way, but make sure you ...

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 ...

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 ...

New research led by academics at the University of Bristol has discovered that the scales on moth wings vibrate and can absorb the sound frequencies used by bats for echolocation (biological sonar).

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 ...
