Cremer's theory of sound transmission for a single‐leaf wall is transformed into a more general formulation in which the exciting pressure is expressed in terms of the spatial cross‐correlation. The correlation coefficient was measured in a reverberation room just in front of the wall under test. The sound‐transmission loss of a single gypsum‐board wall was calculated employing these diffusivity measurements and compared with experimental data. Agreement between theory and experiment is good, especially in the frequency range below the coincidence frequency. Finally, a few fictitious quasidiffuse sound fields are investigated further study of the influence of the degree of diffusivity upon transmission loss.
