Developed by Matelys, TubeCell is specialized acquisition software designed to manage impedance tube measurements in accordance with ISO 10534-2, ASTM E1050-12, and ASTM E2611 standards. It enables users to acquire and post-process data, providing input for further analysis using methods such as Finite Element Method (FEM), Boundary Element Method (BEM), Statistical Energy Analysis (SEA), and Ray Tracing. TubeCell supports arbitrary tube dimensions and microphone positions, accommodating measurements with 1 to 4 microphones. Features include individual microphone calibration, calibration of relative microphone positions, a guided measurement procedure, frequency range overlap averaging, and methods like 2 microphones/2 loads and 3 microphones/2 loads. The software offers full post-processing capabilities, including the computation of uncertainty envelopes and inter-sample dispersion envelopes. Output data encompass surface properties (absorption coefficient, surface impedance, reflection coefficient), transmission coefficient, coherences and auto-spectra, bulk characteristic properties (dynamic mass density, dynamic bulk modulus, characteristic impedance, characteristic wave number), dissipated powers, and transfer matrix coefficients. By reducing the lead time for measurement campaigns and providing true monitoring of measurement quality, TubeCell enhances the efficiency and accuracy of impedance tube measurements.
