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 ...

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, who recently discovered ...

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 ...

This latest accomplishment joins the company’s previously secured ASTM certifications, enhancing the features and expanding the end-uses for its microalgae-based bio-cement and bio-concrete. BOULDER, ...

Good fences make good neighbors, but putting up a picket fence inside a small apartment to help keep the peace between two roommates just isn’t an option. As an alternative, Ikea, which has been all ...

Acoustic metamaterials are artificially structured media engineered to control, direct and manipulate sound waves in ways not possible with natural materials. By arranging subwavelength resonant ...

The breakthrough material reduces a noise level by 100% more efficient comparing to standard analogs, cutting the level of noise transmission by 20-22 dB. The new foam reacts to sound waves not only ...
