to show the following variables capacitors sound waves and electrical signal they give. If you can add a change in voltage and change the sound waves, it would be really perfect.

I tried to read the above web pages, but I can not find the information I need!
Can you provide the relations bewtween, the frequency of the sound wave, voltage, etc.?
I am not an expert in microphone, I need a model in order to create the simulation.
