OBJECTIVES: To assess the amplification and distortion of noise in incubators by measuring noise levels from various sources under various conditions. STUDY DESIGN: We recorded sound pressure levels ...

If you live near a busy street, this new breakthrough from Switzerland could offer some long-awaited relief. Researchers at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) ...

For applications where mounting acoustical wall treatments are impossible or undesirable, ProMAX Panels are lightweight, stand-mounted, portable StudioFoam sound absorbers. They are used in such ...

Hard surfaces and high ceilings are major contributing factors to noisy, echoing spaces. Inhabitat met Kirei founder John Stein at his Greenbuild booth where he explained that designers should ideally ...

The amazing sound-absorption abilities of moths’ wings, which helps them evade bats echolocation calls, has inspired new techniques for manufacturing ultra-thin sound absorbing panels. Scientists at ...

Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.
