New achievements in Testsens' impedance and sound transmission loss tube
Testsens' acoustic characterization software extracts material intrinsic properties from measurements via the Johnson-Champoux-Allard-Lafarge model (JCAL), such as porosity, airflow resistivity, tortuosity, viscous characteristic length, thermal characteristic length and static thermal permeability. These are mostly used by acoustic simulation (CAE) software, and make Testsens a complete solution. Additional available functionalities of the software include the determination of dynamic density and dynamic bulk modulus. The user-friendly software interface provides flexibility of data handling, such as data merging, octave band calculations, corrections and airflow resistivity approximation.
