The diagram of a research is shown in Figure 4. Portable sound and vibration analyzer SVAN 912 was used for noise measurements. During the measurements there was made the registration of the time charts of noise with A correction and step buffer 0.125 s. This feature allowed the graphical representation of changes in the level of noise while zooming in and out of the vehicle from the point of measurement. At the same time it was measured the frequency analysis of noise in one-third octave frequency bands with a linear correction.
