Air Torce is really working—we are now planning additional installation for more noise control! (Air Torce W)
Mr. and Mrs. A live in a house in Saitama. Because their house is right next to a busy street with a lot of traffic, when they open the window, the outside noise comes in, waking up their baby. They were afraid that the noise situation would get worse once their street would be connected to a major road. Furthermore, they wanted to secure consistent air circulation in the living room space on the second floor. They spent most of their time there, and therefore heat tends to accumulate.
