Acoustics of Coupled Rooms Using the Acoustic Diffusion Equation

Application ID: 20171


The behavior of the diffuse sound field in two coupled rooms is investigated using the Acoustic Diffusion Equation interface. The model setup is based on the paper by Xiang and others, J. Acoust. Soc. Am., vol. 126, p. 1187, 2009. The model determines the sound pressure level distribution, energy decay curves, and reverberation time for the two rooms and more. The study is performed in octave bands. The use of the stationary, eigenvalue, and time-dependent study steps is exemplified.

This model example illustrates applications of this type that would nominally be built using the following products:
