In the contribution a method of measurement and dynamic analysis of the recent operational tests of the monobloc wheel with/without damping elements is presented. On the basis of time-frequency analysis of operational vibration and experimental modal analysis of the wheel its dynamic behavior is described. The vibro-acoustic coupling is analyzed from the comparisons of vibration and sound pressure spectrograms. At passing the curve, the formation and modal-frequency composition of squealing noise is observed and there are identified vibrational modes that mostly contribute to noise emission into surrounding. For quantitative comparison of individual wheel solutions the third octave analysis is used.
