Shabaz,

Looks a good circuit. I designed a circuit using electrets many years ago now that was my introduction to these amazingly sensitive devices. I think it was some sort of volume sensor - if you shouted loud enough it activated something. I can't really remember as it was so long ago. The PCB design looks good.

I get the impression microphones are an under-used component in people's microcontroller projects. Most people probably think of only using microphones to record human speech, but I'm sure there's an opportunity for audio outside of human hearing to filter on for a project.

Sounds very good in response. It is worth I try to use a couple of these instead the standard Adafruit boards I used for the ears of Seven of Nine

Nice basic amplifier circuit.
