I have two questions.
I am analysing voice signals using GRAAS microphone, NI9234, cDAQ 9178 & labview 2011. I am trying to produce a two dimensional graph of the signal with SPL (DB)(y-axis) versus frequency (x-axis). I noticed that the SVT sound level.vi from the sound & vibration toolkit outputs into 4 different values;
1. exponential averaging sound level (dB),
2. Leq sound level (dB),
3. running leq sound level (dB), and
4. peak sound level (dB).
Which of this four should I use.
Is it right that I should use linear weightage for human voice analysis?
Thanks in advance
