Noise measurement with DASYLab

Independent of the used measurement hardware the acoustics measurement module calibrate microphones with DASYLab according to DIN IEC 60 651 and DIN IEC60 804.

The common used weighting filters S, F, I, Leq, A, B, C and Lin Z are available as well as a 10Hz high pass filter so that even with a sound card it is possible to measure according to the standards.
