The programme’s funding budget, which runs from 2009 to 2014, is about 130 million Euro. It is financed from the German government’s second economic stimulus package.

No use, even partly, without the consent of the author Environment Accompanying Research Status Conference Angelo D‘Angelico Fon +49 172 7106352 angelo.dangelico@acoustic-consult.com Volume reduction of approaching vehicles considerably higher than expected by the Din standard measurement 362. Main factors for vehicle noise emissions -> Type of engine -> Insulation of vehicles and active noise shaping -> road conditions -> number of start / stop operations. Especially in delivery traffic (many start - stop operations) and small cars considerable reductions are possible. Less potential for middle class and upper class.
