Impedance Tube Parameter Estimation with Data Generation

Application ID: 71561


Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound inlulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two measurement microphones. The model includes an initial study, which generates synthetic measurement data. Noise is added to the data before it is exported.

This model example illustrates applications of this type that would nominally be built using the following products:
