How can I calculate the voltage over a microphone?

I want to make a microphone myself with the Arduino (capsule=microphone):

enter image description here

I have bought the following as microphone: http://www.farnell.com/datasheets/1660938.pdf

As is in the datasheet the microphone operating voltage is between 1.5 and 10 volts. The problem is how do I calculate what resistor do I use to get that voltage? I can't use it as a voltage divider (the resistor with the microphone) right?

P.S. I have resistors laying around between 10 ohm until 10 Mohm so that won't be a problem ;)
