In Part 5 of this 9-part course on modeling pressure acoustics in COMSOL Multiphysics®, we continue using a version of the room acoustics model from the previous video, which was modified to model the acoustics in an open space. In this video, you will learn about the Background Pressure Field feature and how to use it for scattered field analysis. Using the feature enables you to model a background or incident pressure field to study the scattered pressure field.
