This looks like it might work.
If you're using an electret microphone.

Look at the schematic near the bottom.

Hi Kamikaze,
If you want to consider another circuit, goto www.aaroncake.net/circuits and search for SOUND LEVEL METER. Where the input to the bar graph is you could feed that into a PIC analog pin and go from there.
There are many published articles for what you want to do but I think after looking at Darrel's and mine you should be able to accomplish what you are looking to do.
Did you get your other LCD project going? I was referring to using a serial LCD. Sparkfun has one very reasonably priced and very easy to work with.
HTH,

Thanks Darrel and BobK. I'll have a look at both of those now, and i'm sure i'll work it out.
I got the LCD going. In the end i opted the easy way out and went with an 18-pin PIC instead of the 8-pin i wanted to use - Mainly to minimize the physical size of the circuit.
