  • Resistive screen and fabric holder

    Are you planning on measuring sound absorption or sound transmission of thin screens, fabrics, and clamping plates on air cavity backing of variable depths? Do you have problem controlling acoustical edge leaks when measuring the absorption of thin porous materials? Do you need to identify the flow resistance and porosity of permeable screens from impedance/transmission tube testings? Mecanum’s resistive screen and fabric holder is what you need. Combined with FOAM-X, you will be able to characterize and model any screen or fabric with high accuracy.

  • Porous Material Slicer

    Mecanum porous material slicer allows you to easily slice your porous materials to the recommended thickness for the following equiments:

    • Impedance and transmission tube
    • Airflow resistance meter
    • Tortuosity meter
    • Porosity meter
    • Quasi-static mechanical analyzer

For 44-mm diameter sample
For 100-mm diameter sample
  • Grids and rings

    Especially designed rings to minimize acoustical or airflow leaks around the sample in impedance/transmission tube and airflow resistance meter. The rings can be installed on the front, the rear, or both the front and rear faces of the sample to test. Different sizes are available. Each ring is distributed in pair.

    Specially designed grids to support limp materials (eg. fluffy fibers, granules) or to control thickness of fiber materials (eg. glasswool, felt, shoddy). They also minimize edge acoustical or airflow leaks. The grids can be installed on the front, the rear, or both the front and rear faces of the sample to test.

    Note that Mecanum’s TUBE-X software may also eliminate the effects of rings and grids. This allows the user to determine with accuracy the intrinsic acoustic properties of the tested material sample only.

  • Enviro Weather Station

    Mecanum’s Enviro Weather Station allows you to measure the atmospheric conditions of the air (i.e. pressure, temperature, humidity) in order to deduce their acoustic and thermodynamic properties. The integration in our software suite is completely seamless (i.e. automatic reading of the weather station when the software needs it).

  • Modification of existing impedance tube to the 3-microphone method

    Mecanum modifies existing tube such as B&K impedance tube to the latest transmission measurement technologies using the three-microphone two-cavity method (3M2C) which uses equations of ASTM E2611. The method is published in peer reviewed Journal of the Acoustical Society of America. Follow the links to access the 3M2C method, and its application for porous material characterization.
