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:
