Abstract

The article presents the problem of the testing of some protective systems made of PU foam based composite materials which can simultaneously meet the following requirements: noise absorption for middle and high range frequencies, noise insulation for low frequencies, vibration damping in order to avoid noise transmission by structure. There are presented experimental data of the efficiency of the acoustic treatment applied for the cabin of the Romanian frontal loader MMT45.
