To address mid and high frequency range, other methods have to be implemented such as Statistical Energy Analysis (SEA). This paper concentrates on impact sound insulation prediction in the low frequency range by means of FE simulations and presents first validation steps for a wooden floor identified as representative in Europe. The main difficulties in impact sound insulation prediction are identified and discussed.
