In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it ...

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 ...

Engineers have demonstrated that a fully open ventilation channel can absorb most incoming sound across a broad range of frequencies. That result breaks a long-standing tradeoff between airflow and ...

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 ...

(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 ...

Belgian acoustics specialists Kahle put sound centre-stage, sharing what's at stake acoustically when it comes to performance ...

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 ...

(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 ...

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 ...

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 ...
