Using sound to create a physical output

Good afternoon. Im relatively new to Arduino and have only used sound components a couple of times.

Im looking into creating a device that allows me use sound as an input e.g. sound into a microphone or similar. That then produces an output such as physical action (up or down movement) used from a servo motor or similar.

Is this possible or does anyone have any recommendations?

cheers guys.

Yes, this is possible.
