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 ...

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 ...

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 ...

Deep-subwavelength acoustic absorbers have received great attention due to their scientific and application values. Porous materials and micro-perforated absorbers, as the most conventional solutions, ...

(Nanowerk News) 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 ...

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 ...

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 ...
