In case you’re sensitive to noise and look for a discreet way to solve the problem in your apartment or office building, for example, the so-called Feltone [JP] might do the trick for you. Developed by Japan-based Tokyo Blinds, Feltone is a blind that can absorb sound and push down power noise by up to 60%.
Feltone, which is – as the name suggests – made of felt, looks like an ordinary blind and can be used on windows or walls – just like conventional blinds, without any special modifications. Tokyo Blinds says installation takes about two hours, with their solution costing up to 90% less than soundproof panels, for example.
The company explains:
This sound-absorbing blind works because sound is absorbed extremely well if there’s a rear air layer, 50-200 mm thick, between the blind slats and a wall, when the blind is attached in the usual way. We’ve utilized this phenomenon to achieve an effect like a sound-absorbing panel, by adding sound-absorbing felt.
Feltone (which is available in Japan only at this point) doesn’t come cheap: a 2mx2m blind costs $1,500. Since 2009, Tokyo Blinds has been marketing the blind to home theater owners, companies (for meeting rooms, server rooms etc.), families with children, etc.
