Noise-reducing measures on vehicles used in urban areas are particularly effective.Four years of work have resulted in the development of a noise-reducing capsule for our distribution trucks with 6 to 10 tons g.v.w. (Class 3 to Class 6). This capsule reduces the drive-past noise by approx. 6 dB(A) and at the same time reduces the noise level in the cab by approx. 3 dB(A).All component temperatures remain inside the permissible ranges; the functionability of vehicles with capsules is retained in full. The dead weight of the trucks is increased by approx. 40 kg.
