基于阻抗管测量的多孔材料特性
Application ID: 142771
This app is an example of how the poroelastic properties of a porous material can be determined based on measurement done with an impedance tube and parameter estimation.
Being able to determine the characteristics of a porous material from a single and simple measurement opens the door for simulations with accurate boundary conditions. The parameters obtained through this app can be used directly in other models with the Poroacoustics feature.
The porous material investigated here was provided by ROCKWOOL A/S, and the impedance tube measurement was performed by Hottinger Brüel & Kjær A/S.
