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 ...

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 ...

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).

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 ...

These sound absorbers are offered in several custom designs and can be attached to ceilings or walls using an aluminum C-channel. Constructed using willtec foam, features include: Excellent sound ...

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 ...

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