Measured Properties


  • Analysis of the acoustic nonlinear response of materials

  • Quality control

  • R&D applications



Standard Mecanum’s impedance and transmission tube system includes:

  • Impedance and transmission tube;

  • Microphones;

  • DAQ system;

  • Ultralow distortion audio amplifier;

  • TUBE-X software;

  • Verification sample to check the measurement procedure;

  • Grids to support limp materials;

  • Rings to minimize acoustical leaks around the sample.

TUBE-X Software


The TUBE-X software is a user-friendly tool for impedance tube measurements. It will allow you to choose among different measurement techniques. TUBE-X controls the entire procedure from calibration to the measurement itself. It takes into account the atmospheric conditions and the internal dissipation of the tube.

TUBE-X can also:

  • Measure in white noise or sine sweep;

  • Correct the effects of grids and rings if they are used during measurement;

  • Compare measurement projects;

  • Merge the measurements made with the different tubes;

  • Average measurements (in fine bands, third octave and octave);

  • Estimate acoustic indicators (NRC, SAA);

  • Calculate the penetration depth of the acoustic wave in the material (20 dB reduction);

  • Export graphs and data to Excel and text files.
