One-Family House Acoustics

Application ID: 20169

This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two story one-family house consisting of 10 rooms is analyzed.

The steady state sound pressure level (acoustic energy density) distribution is analyzed for a sound source located in the main living room. The reverberation time T60 of the different coupled rooms is then studied using the eigenvalue solver. The transient energy decay (curves) is also found using a time dependent study. Finally, the sound pressure level radiated outside the house is determined with a coupling to the Ray Acoustics interface.

Wall absorption parameters, transmission losses, and material parameters are values assumed to be realistic for the model.

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