Transfer Matrix of a Tube and Coupler Measurement Setup
Application ID: 104291
This tutorial computes the transfer matrix of a tube and coupler measurement test setup. This type of setup is used for standardized testing, for example, for miniature loudspeakers or hearing aids.
The Port boundary condition in Pressure Acoustics, Frequency Domain is used together with the Port sweep functionality to automatically extract all four transfer matrix elements.
The computed transfer matrix is exported to a text file. The generated data is used in the Balanced Armature Transducer tutorial model to simplify the model setup using the Lumped Port feature.
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. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
