The aim of the work reported in this paper is to establish a method of determining the diffusivity of an SEA subsystem using the phase of transfer functions. Specifically, this paper reports an investigation into the phase characteristics of transfer functions obtained using two flat plate structures. In the first experiment the phase characteristics of bending waves in a directional field are obtained using a perspex plate with additive damping. In the second experiment the phase characteristics of bending waves in a diffuse field are obtained from a freely suspended steel plate. The experimental data are normalised and compared to theoretical formula and limits for the diffuse field and direct field proposed.
