I am recording voice signals using Apex440 Class-A FET cardioids condenser microphone directly connected to my computer via USB. I have written the labview vi (data acquisition) using sound input read which has successfully read the waveform. (vi attached)
The microphone has a sensitivity of -40dB = to 10mV/Pa. When recording voice, the maximum amplitude in the graph is around 0.15-0.2. How can I include the sensitivity value in the vi, so that the y axis represents SPL value?
Using Labview 2011 (32 bit) on a Window 7 machine.
Thanks

You can include it in Y-Axis's Scaling settings:
