Aircraft noise is often a problem which citizens prot to strong and expensive measures (flight bans with high intake precipitation) leads in airports. The environmentally compatible design of houses is also very expensive; as well as the heating costs.The many years of protests and processes with respect to the frankfurt airport (fra) show that the solution is by no means obvious to those skilled in the art: high ultimate tensile solid, transparent films, for example, by slight pressure which, on kevlar - high pressure - 20c of the racket frame, a suspended position, as a rule with several layers of air - intermediate layers for insulation against noise and heat losses, of several hundred to a few kilometers length in the 30 – 100 meters in height, heat recovery, flaps in the roof, fresh air supply (ecologically optimized), a - and extending cylinder locks (noise separation) for cars and busses generate a residential experience " without noise generated by ‘ perpetual spring. An optionally to the directions of flight optimized outer shape causes an additional reflection of the sound waves to the top (principle of stealth - aircraft). The solution itself provides futuristic from is, however, in the components, present. The innovation is the integration of the components to be somewhat completely new cities ‘ perpetual spring ", which for the local residents are even less costly than previous houses with expensive insulating measures -.
