Physiotherapy ultrasound machines are commonplace in medicine and sports injury treatment but limitations with current calibration equipment mean they may be producing inaccurate doses that could lead ...

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 ...

Complete sound attenuation by dissipation usually requires thick absorbing materials, with dimensions comparable to the wavelength of low-frequency airborne sound (typically 1–10 m). However, it ...

Washington, D.C., Feb. 9, 2016 - 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 ...

New research led by academics at the University of Bristol has discovered that the scales on moth wings vibrate and can absorb the sound frequencies used by bats for echolocation (biological sonar).

Noisy offices can be transformed into productive workplaces through the range of acoustic systems for walls, floors and ...

The Thinsulate Compressible (TC) Series of proprietary, low-density, highperformance nonwoven acoustic absorbers are cavity filling, compressible, and conformable. This makes them well suited for ...

The Vancouver, B.C.-based audio company Primacoustic is an established manufacturer of acoustics products for the pro sound and residential home theater markets. Recently, the Canadian manufacturer ...

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 ...
