How to configure ADC on mbed

I have a Sensitive Microphone Sensor Module which I got from an Arduino kit and I want to connect it to my mbed ADC and monitor the output.

I am building a Beehive environment monitoring kit using the mbed. I have got the temperature and humidity part working but now want to monitor the sound levels of the beehive.

The Mic module has a A0, G and + pins. I just need a little help in how to wire this up to my mbed and how to read values from the output of the module. I guess all I want to find out is what is the db level of the surrounding sound.

I know this may seam trivial but it's a long time since I did any electronics.

I would be also grateful for any pointers for any other sound modules which would be better suited for my project.

Any help would be very much appreciated.

Cheers Charlie
