Input Impedance of a Tube and Coupler Measurement Setup: Time Domain MOR using Partial Fraction Fit
Application ID: 129911
This model computes the input impedance/admittance to an acoustic system in the frequency domain. The system here represents a typical measurement setup used for testing hearing aids and includes domains with thermoviscous boundary layer losses.
The input admittance, computed in the frequency domain, is fitted using the Partial Fraction Fit function. Then an equivalent electrical circuit model is set up to demonstrate a powerful model order reduction (MOR) approach. The circuit is here automatically generated using a method call.
The equivalent circuit can be used to represent the input impedance/admittance of the measurement system in time domain simulations, including the frequency dependent thermoviscous damping.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
