Samenvatting

To obtain detailed information on the modal behavior of the floor and on the influence of the impact source, narrow-band sound pressure level measurements are performed on a concrete base floor and a floating floor. Various tapping machine positions are considered and the results are averaged over several microphone positions for each tapping machine position in order to reduce the influence of the spatial distribution of the sound pressure in the receiver room. Both the finite element method and a novel prediction method for impact sound transmission, termed the modal Transfer Matrix Method, or mTMM, are used to interpret and investigate the measurement results. The mTMM can be combined with a detailed source model and accounts for the finite dimensions of the layered floors. The measurement results of the layered floor clearly indicate the importance of considering all five impact hammer locations of the tapping machine to achieve a high prediction accuracy, especially at low frequencies. The influence of the impact source and the modal behavior of the floor can lead to pronounced peaks in the radiated sound power level.
