Abstract
In this paper Cremer's model1 that describes two infinite parallel plates surrounding a spring-like interlayer is examined. A point force excites the top of the two plates, both of which are assumed to support only bending waves due to neglecting rotary motion and sheer deformation. The wavenumber, which gives valuable information about the propagation and damping of waves, is examined in both a high and low frequency range. The theoretically obtained wavenumbers are compared to those gained from measurements on a wood joist floor. How an applied topping, simulated by the top plate, modifies the calculated and measured wavenumbers is described.
