We've utilized this phenomenon to achieve an effect like a sound-absorbing panel, by adding sound-absorbing felt. So this blind absorbs sound very easily using that effect." Feltone is the same size as an ordinary blind, so it can be easily attached to windows and walls. It can also be rolled up and removed.
The degree of sound reflection can also be varied, by opening and closing the slats. This makes it possible to adjust the noise level by varying the reflectivity, which has been difficult to achieve with soundproof panels.
But there are very few ways to solve those kinds of problems. If people with a noise problem consult us, what we do is: We simulate all the possible solutions, and compare the current noise situation with a simulation of the noise level if our products are installed in the room."
A 2m x 2m Feltone blind without a cover costs about 120,000 yen. Blinds can also be made to order. Feltone blinds can be installed in around two hours, for one-third to one-tenth the cost of ordinary soundproof panels. From now on, Tokyo Blinds plans to release sound-absorbing curtains, as well as sound-absorbing low partitions designed for meeting rooms and offices. (DigInfo)
