sound - electricity?
ars: Wind essentially IS sound - but with a very low frequency.Sound is air moving, wind is air moving.You can use a turbine that spins forward and back I suppose. You'll have a hard time with this - you'll need to match your turbine to the frequency of the sound. Using a microphone works, but only for frequencies in human range.If you want to catch more energy you'll need to handle infra-sound. Meaning a massive microphone.
