If you’re sensitive to noise and realize a discreet thanks to solve the matter in your apartment or workplace building, for instance, Felton referred to as will do the trick for you. Developed by Japan-based Tokyo Blinds, Felton may be a blind man who will absorb the sound and push down on the noise energy by up to hour.
Felton, who is – because the name suggests – felt, as a stream is blind and might be used on windows or walls – similar to typical blinds, with none special modifications. Blinds Tokyo says that the installation takes concerning 2 hours, the answer value up to ninetieth but the insulation panels, for instance.
The company explains:
The sound absorbing blind works as a result of the sound is absorbed fine if there’s a rear air layer, 50-200 mm thick, between the blind and wall slats when the blind is hooked up within the usual means. we tend to used this phenomenon to realize a bearing sort of a sound-absorbing panel, adding sound-absorbing impact.

Felton is obtainable solely in Japan at this point) isn’t cheap: it prices $ one,500 a blind 2mX2m. Since 2009, Blinds Tokyo has been promoting the blind to the house owners of home theater, business (for meeting rooms, server rooms, etc.), families with youngsters, etc.
Sounds good but they seem to forget something and that is that the thin felt will only absorb the highest of frequencies. As a result, the acoustics of the room will be even worse than before – absorbing only the highest frequencies but leaving everything else.
Human voice concists of frequencies between 250 to 3000 Hz and the most energy is in the lower part of that range. Those blindes does not have a chance to effectively absorb the lower part and what happens is that most of the echoes will reamain, apart from the higher frequencies, leaving you with an even odder acoustic environement.
When absorbing sound (voice, music and so on) it is extremely important to do this evenly throughout the frequencies, using real sound absorbers and not putting them up on a whole wall but sparsely and where it does the most effect. Look at the Skype spin-off Sounds Of Science: http://www.sofsci.com/ for a good example.
Thus big areas with this kind of blindes is not a good solution, for many reasons.
