Acoustic absorption is a fundamental parameter in the evaluation and optimisation of noise control within various environments. Recent advances have improved our ability to characterise how materials ...

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 ...

Researchers have recently developed a design for a coiled-up acoustic metasurface which can achieve total acoustic absorption in very low-frequency ranges. Researchers at the French National Centre ...

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 ...

April 26, 2007 - Elk River, MN - Ready Acoustics announced today a series of new acoustic treatment products aimed at providing user-customizable aesthetic options for Home Theaters, Studios, Church’s ...

(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 ...

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, ...

Acoustical comfort is a critical element of interior design that should never be neglected, especially in shared spaces such as restaurants, convention centers, museums, sports halls, and many others.

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 ...
