SLM & SPM
PC based Soundlevel meter / Soundpower meter in real time
SLM & SPM Description
Based on DASYLab ROGA-Instruments offers modules for SLM and SPM.
Independent of the selected measurement hardware the sound level module (sound level measurement) calibrates according to DIN IEC 60651 & DIN IEC 60804 when used with DASYLab. The
commonly used weighting filters S, F, I, Leq,Peak, A, B, and C and a 10 kHz high pass filter is available so even with a sound card measurements can be made which conform to the
standard.
The level values measured with the sound meter can now passed over to the sound pressure meter in multi channel form. After applying the envelope method the sound pressure values can be
output online (i.e. Lw(A)).
