This work presents the results of the statistical analysis of noise in several points of GAZ-3110 vehicles. There are also the dependences between the loudness of noise and speed of an engine or useful life of a car. It is difficult to confuse the noise of jet engine with reciprocating internal-combustion engine. Random factors also influence much the power level. Mechanism adjustment has its limits and so it can have different influence on its vibration and noise. Finally during the process of operation sliding surfaces do wear, screwed connections do loosen, other things happen and these lead to the changes in spectrum and level of noise. In this work we tried to evaluate the dispersion of GAZ-3110 vehicles noise levels according to the results of a coustic measurements in the immediate field of rondom acoustically active constructive assemblies. The range of noise loudness for the specific car model is defined at the level 20-25 dBA. The GAZ-3110 vehicles are characterized by the significant dispersion of noise level. The differences of noise level of individual cars are exceeding 20-25 dBA. vehicles noise considerably increases with the augmentation of useful life and rpm speed. The noisiest element of GAZ-3110 vehicles is internal combustion engine, then main gear even when first gear is operated.
