Issue Details

I am performing the same acoustic measurements with LabVIEW and with another software.
I can see a shift between the measured values, why?


There are several possibilities that could lead to this problem:
  • Verify that the other software you use follow the same norms as LabVIEW, which are:
    • ANSI S1.4-1983
    • ANSI S1.42-2001
    • IEC 61672-1:2002
    • JIS C 1509-1:2005
  • Verify you are performing the measurements with strictly the same hardware configuration
  • Verify that you are following the same calculation procedureĀ as the other software
