SIDLAB 4 Release Highlights

SIDLAB 4.4.1 Release Highlights

  1. Fixed a backward compatibility issue.
  2. Fixed an issue with white noise excitation.
  3. Fixed an issue with High Frequency licensing.

SIDLAB 4.4.0 Release Highlights

  1. New measurement configuration for 3-port mufflers: Using configuration 5, 3-port mufflers can be measured simultaneously by connecting the new SIDLAB test rig designed specially for this type of mufflers. No need to dissemble half of the rig and assemble it with other port to measure the full performance of the 3-port muffler, just assemble the new rig to the muffler ports and use SIDLAB to acquire all the data and SIDLAB will do full characterization of your muffler using 3X3 matrices.
  2. New technique for extending the measurement range: In the old versions of SIDLAB Acquisition, the measurement frequency range is determined by the limit of low frequency and high frequency microphones spacing, taking into consideration a necessity of overlap between the tow ranges. In this version, a new technique based on least squares is developed to allow for a frequency gap between the two ranges which extend the measurement range of the test rig for all configurations.
  3. New lined duct element with variable lining thickness: The new model is based in AHRI standard which provides model with variable lining thickness. This will allow more flexibility in the simulation instead of fixed one-inch lining.
  4. Improvements for the liquid fluids results.
  5. Improvements in IC Engine model.
  6. High Frequency results are exported automatically in table format in more details.
  7. Improvement for flow noise results in High Frequency module.
  8. Licensing improvements.
  9. Updated MATLAB runtime engine MCR 2020a.
  10. High Frequency elements improvement.
  11. Bug fixes.

SIDLAB 4.3.0 Release Highlights

  1. New Module: Sound Transmission Class (STC) measurement, available in SIDLAB Measurement License.
  2. Calculations through Command Line Interface CLI for SIDLAB Acoustics and Flow.
  3. Licensing improvements.
  4. Automatic updates for new versions.
  5. Updated MATLAB runtime engine to MCR 2019a.
  6. Updated License Agreement.
  7. New Help viewer.
  8. Updates in Simulation and Acquisition Help content.
  9. New measurements tutorial.
  10. Bug fixes.

SIDLAB 4.2.1 Release Highlights

Bug Fixes

SIDLAB 4.2.0 Release Highlights


  1. Faster start of SIDLAB.
  2. Smoother activation of SIDLAB, enhanced MAC address selection for activation code requests.
  3. Optimized view in the network Tab to better view the properties of the elements.
  4. Better support for Chinese Language.
  5. Better presentation of the Flow results plots.
  6. Easier definition of the location of the receiver position in the High Frequency Analysis with respect to the muffler opening or Grilles and Terminal Diffusers in HVAC applications.

  12. Fixed an issue with plotting the coherence directly after measurements in SIDLAB Acquisition.
  13. Fixed an issue with the location of the pressure taps on the rig dimensions Tab in SIDLAB Acquisition.
  14. Fixed an issue with the last frequency when using the Lined Duct Element.
  15. Fixed an issue with opening SIDLAB project files from Windows Explorer.
  16. Fixed Several Minor Bugs.
