The Swell acoustic panels are designed to be used as lightweight sound absorbers in the upper frequency range (500 Hz and above). They are well suited to eliminate disturbing reflections of environmental voice sounds, telephones and computer disk drives etc. They can also be used to improve privacy in an open work area such as a modern office space or a restaurant. The panels, made of a moulded polyester fibre, are available in a grey, anthracite or off-white color. Here is an install image http://azure-usa.com/scrunchenvironment1
