Developed by Matelys, RoKCell is designed to characterize the acoustic parameters of porous materials, fabrics, perforated plates, and liners using impedance tube measurements. It provides insights into dissipation mechanisms and generates input data for various analysis methods, including Transfer Matrix Method (TMM), Finite Element Method (FEM), and Lattice Boltzmann computations. RoKCell employs analytical inversion techniques based on the Johnson-Champoux-Allard-Lafarge (JCAL) model parameters, offering features such as Bayesian minimization, parameter consistency checks, and uncertainty computations. The software supports export to formats compatible with tools like Actran and LaTeX. Additionally, RoKCell includes a finite element computation module to estimate bonding or leakage effects during measurements.

Features:

• Analytical Inversion: Utilizes analytical inversion techniques to determine JCAL model parameters.
• Bayesian Minimization: Incorporates Bayesian minimization for enhanced parameter estimation.
• Parameter Consistency Checks: Ensures the reliability of characterized parameters through consistency checks.
• Uncertainty Computation: Calculates characterization uncertainties to assess measurement reliability.
• Finite Element Computation: Estimates bonding or leakage effects during measurements using finite element analysis.
• Data Export: Supports export to TXT, Actran, and LaTeX formats for seamless integration with other analysis tools.
