Designed by Tapio Anttila and Woodnotes Design team, Whisper is an acoustic interior panel. The appearance of these panels can be changed with the choice of different colours, sizes, and thicknesses giving a three dimensional effect to the panels. Almost unlimited choices make it possible to create an individual panel installation for different interior solutions. This environmentally friendly acoustic panel is made from pure and safe raw materials: wooden frame and cellulose-based manufacturing process by-product that is fireproof, emission free, acoustic and eminently suitable for people with allergies. The panels are upholstered with the Sand paper yarn fabric and are available in 9 colours. A new Sand upholstery fabric colour, brass, is introduced.
