Due to the cost of property and the economy, some people end up staying in places that while not ideal, are within their budget. Such non-ideal locations include staying near the airport or by the highway which is not only incredibly dusty and the roar of plane and car engines can get on your nerves. Tokyo Blinds, a company from Japan, has come up with a set of window blinds called Feltone. As the name implies, these blinds are made out of felt and the company claims that this would help to absorb sound waves and even converting them to thermal energy through repeated reflection. It is said to be able to reduce sound levels at 89dB by 4dB.
Ubergizmo, Feltone window blinds will help soundproof your house
