The paper deals with the results of experimental research focused on the assessment of the influence of fibreglass layers on the efficiency of plate vibration and noise dampers. The influence on vibration reduction is evaluated on the base of frequency response functions and 1/3 octave band analysis of averaged autospectra of velocity of vibrations, the influence on acoustic emission is evaluated on the base of 1/3 octave analysis of averaged spectra of acoustic pressure and acoustic power.
