I don't understand why the particular values of the components are used

And the mic converts the sound signals into electrical signals to feed to the amplifier circuit.

The 0.1μf capacitor is used to couple the input signal with the base of the Q1 transistor. I don't know why R1 is used.

I've already constructed the PCB of the circuit. And now all I've got to do is to write a report where I must mention the functioning of every component. I'm not so good in electronics. :(

Attached with this post is a picture of an [FONT="Verdana"]intercom circuit using only transistors. It is a two-staged coupled amplifier circuit. I have constructed this circuit for my college physics project. But for the report I want to know the functionality of every component of the circuit...
