The publication presents the results of research on the statistically significant impact of the number of layers on vibration damping properties of vibroacoustic mats. The research was carried out on the author's research stand. The research was carried out on sandwich systems made of polyurethane foam. The impact force of the analyzed variables was determined on the basis of constructed multiple regression models, the so-called multifactor models and determination of the standardized value β. The research was carried out using the PQStat software. In the models being built, the significance level was p < 0.05. Three statistically significant linear multivariate models for one-third frequencies were constructed: • 0-20000 Hz - a model for the entire frequency spectrum analysed during the tests, • 0-400 Hz - a model for frequencies generating construction vibrations that may affect the worker as general vibrations, • 50-20000 Hz – a model for frequencies that generate construction vibrations that can cause auditory sensations (noise). It was found: positive correlation of the number of layers in vibration damping systems with a third octave frequency of up to 400 Hz; negative correlation of the number of layers in vibration damping systems with a third octave frequency of 50 to 20000 Hz.
