ABSTRACT : In this paper the fairly interesting method for noise reduction of motor vehicles in use based on the determination of acoustic potential of motor vehicle components is presented. The method relies on synergic model of noise generation as a complex function in time. The arbitrary number of motor vehicle noise sources act in concert yielding the generation of the overall noise level of motor vehicle thereafter. The number of noise sources participating in the overall noise level of motor vehicle is subjected to the only constraint i.e. the calculation of the acoustic potential of each noise source under consideration. The recast form of the appropriate set of equations describing the synergic model is set forth and solved by dint of Gauss method. The bunch of results emerged and some of them i.e. those ensuing from model application to articulated low-floor city bus designed and manufactured by MDD FAP P r i b o j, company are presented.
