Acoustic Modeling Approaches for Ear /Ear Canal Simulation using COMSOL Multiphysics - Mads Jensen

Synopsis: In this presentation we will look at the physics involved when modeling ear and ear canal simulators. This includes the acoustic thermal and viscous boundary layer losses that define the damping properties of narrow regions. We will investigate how to set up and model a BK Type 4157 ear simulator (the so-called 711 coupler) using COMSOL Multiphysics. Finally, we will look at ways to use the results in a virtual test setup. This includes a full 3D simulation as well as how to identify, compute, and use lumped representations. To deliver quality sound, it is essential to analyze the sound produced by your device during the development phase as well as ensuring the audio quality is maintained during manufacturing. A multitude of parameters are critical to authentic sound reproduction.
