2. Overview

• The steady state sound pressure level distribution from a TV in a two-room
apartment is computed
• The simulation uses the Acoustic Diffusion Equation interface
• An approximate expression for the direct sound is added in the living room

3. Geometry and Mesh

• The geometry consists of a living room, a bedroom, and some
rudimentary furniture
• The acoustic diffusion equation does not have any strong demands
on the mesh

4. Physics

• The simulation is driven by an energy flux assigned to the speaker fronts
• Both rooms have their diffusion coefficient calculated using the cubic room
mean free path model:
c = speed of sound
