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

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 ...

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Stabilized Aluminum Foam is a unique looking material that combines the aesthetics of aluminum (its texture, shades and brightness) with a spongy, porous appearance. It is produced by injecting air ...

A research team from the Department of Functional Composites in Composites Research Division at Korea Institute of Materials Science (KIMS) has successfully developed electromagnetic wave absorbers ...

The most exciting thing to buy at Ikea right now? Believe it or not, it just might be a set of curtains. But that’s because these new draps do more than block out light — they also absorb sound.
