A method involving the evaluation of the cross-correlation function has been developed, which describes the diffusivity of direct sound radiation. The dependence of the spatial correlation of the radiation field on sound source properties and frequency has been investigated. This work highlights the diffuse nature of the sound field of a distributed mode loudspeaker and the correlated output of a conventional cone loudspeaker.:
