This paper describes a procedure for evaluating the reduction in impact sound pressure level of floating floors by measuring resilient layers dynamic stifness according to International Standard EN 29052-1. The possibility to compare impact sound pressure level experimental data obtained in IEN "Galileo Ferraris" laboratories, according to International Standard UNI EN ISO 140-8, with data estimated on the basis of dynamic stiffness measurement has allowed to confirm the empirical model effectiveness. Besides, two main questions are investigated: mass-spring analogous system resonance frequency time depending, i.e. the layer thickness decreasing due to the load as well and the possible relationship between the resilient layer damping ratio with the improvement curve slope.
