Features

Standard Mecanum’s asphalt inpedance tube system includes:

  • 100 mm impedance tube with its speaker and two microphone stands;

  • Flat calibration according to ISO 13492;

  • Asphalt adapter with moistened clay paste for sealing according to ISO 13492-2;

  • Set of handles for easy handling and protection of the microphone;

  • Robust transport case;

  • USB2 data acquisition system;

  • Two (2) ¼ "ICP microphones with calibration certifications;

  • One (1) verification sample per tube and its verification table;

  • TUBE-X software;

  • TUBE-X module for measuring asphalt (ISO 13492-2).

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 sweep sines;

  • 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.
