| Hello,
we've installed EASERA 1.1.3 for checking spurious noise of our products in both the developing and the production state (documentation).
We own a quiet unechoic chamber with about 12m³ volume. We measure through 1" B&K or Gefell microphones using a Norsonic 116 SPLmeter. From its linear output we feed a Griffin iMIC USB soundcard-"MIC" input for low SPLevels. The problem is the bad correlation between the readings on the Norsoninc ("A"- weighted) and the EASERA readings depending on the kind of generated noise. Usually we read levels of about 20 to 40dBA-SPL.
Can anyone explain which settings in the EASERA SW can emulated the analog integration of the Norsonic best?
Thanks for help |
