ELI5, why can’t we convert sound to electrical energy for use? I know microphones convert sound to electrical signals but why is producing energy from waste sound not viable?

Question

ELI5, why can’t we convert sound to electrical energy for use? I know microphones convert sound to electrical signals but why is producing energy from waste sound not viable?

In: Physics

Answer 1

Microphones do that on a small scale, the problem is that sound energy is so much weaker than general wind energy that sound energy isn’t really a viable power source.
