Sonic waves can actually produce electric power by using Piezoelectric material, which means this material will make a potential difference (Produce Electrical Power) when it is exposed to vibration so by blasting a high frequency sonic waves we can produce electricity, too bad this piezoelectric sensor can only produce a very small amount of power which mostly used as a sensor, but who knows the future we will ended up inventing electricity from noise, I hope this explains a little, but your question is a bit difficult if you could clear it up I care to help
