WASHINGTON, D.C., October 6, 2017 -- If you've ever lived in an apartment building or stayed in a hotel room, you are probably familiar with the inconvenience of inadequate sound absorption. 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 ...

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.

On April 22, KCC announced the launch of its perforated sound-absorbing gypsum board, "Soundwin Zero," which enhances both design and sound absorption performance. Perforated sound-absorbing gypsum ...

(Nanowerk News) 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 ...

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 ...

(Nanowerk News) Researchers at the French National Centre for Scientific Research, CNRS, and the University of Lorraine have recently developed a design for a coiled-up acoustic metasurface which can ...
