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
That’s sorta what wind turbines do. However, it’s not as electrically efficient to take high frequency sound waves as an air movement energy source as it is to take constant speed wind as an energy source. It’s not viable because there are larger amounts of air movement energy available from other sources.
