Modeling Speaker-Room Performance in COMSOL Multiphysics^®

In this 6-part, self-paced course, learn how to model the performance of a speaker in a room at lower frequencies with the finite element Method (FEM), and at higher frequencies using acoustic ray tracing. You will be shown how to combine FEM and ray tracing to get a more complete picture of speaker-room performance.

Part 1: Using FEM to Model Speaker-Room Performance

• Outlines the options for numerical analysis of speakers in working environments
• Describes how to model a loudspeaker in a room with FEM

Part 2: Using Acoustic Ray Tracing to Model Speaker-Room Performance

• Describes how ray tracing can be used to complement FEM
• Presents two point source and two surface source methods for ray acoustics

Part 3: Modeling Acoustic Ray Tracing: Release from Exterior Field Calculation

• Provides information about the source model used to extract point sources for ray acoustics
• Walks through the Release from Exterior Field Calculation method

Part 4: Modeling Acoustic Ray Tracing: Source with Directivity

• Provides the steps for the Source with Directivity method
• Compares the Source with Directivity and Release from Exterior Field Calculation point source methods

Part 5: Modeling Acoustic Ray Tracing: Release from Pressure Field

• Outlines the setup of the source model used to compute surface sources for ray acoustics
• Covers the steps to use the Release from Pressure Field method

Part 6: Modeling Acoustic Ray Tracing: Release from Boundary

• Provides the steps for the Release from Boundary method
• Compares the Release from Pressure Field and Release from Boundary surface source methods
