It is shown that the presence of lightweight walls have an influence on the loss factor of concrete floors, especially at low frequencies. Measurement results and theoretical deliberations also show that the coupling loss factor depends on the design and construction of the walls. Furthermore, it is shown that the coupling loss factor increase is due mainly to the energy transmission through the partitions as longitudinal waves; the bending waves are less significant in this respect.
