Abstract This report is of a research project on noise reduction measures concerning sludge-suction vehicles used in street cleaning. The sound power of the vehicles was determined by different methods. Starting from comprehensive measurements, a ranking of the noise sources was performed, which is the foundation of the noise-reducing measures described. The measures presented in the report resulted in the reduction of the sound pressure level by 20-78dB(A). In addition, the A-weighted sound power could be reduced by 19dB(A).
