Thank you @Baluncore @berkeman and @renormalize for your answers.
I have done quite a bit of experimentation in piezoelectricity, but I haven't been able to generate any substantial (as substantial as piezoelectricity can get) amounts of electricity from sound using piezoelectrics. However, I...
Maybe I'm crazy, but due to the high amount of entropy in these different sources (louder sound results in more entropy etc.) is there a way to capture all this unused, "wasted" energy around us? I recently watched a video by Veritasium on YouTube talking about entropy. Do you think this is...
I'm looking for some method to focus a variety of sound frequencies in the environment via metamaterials, parabolic reflectors, Helmholtz resonators, or some sort of device that can somewhat "attract" sound from it's regular path. I've heard about Schumann resonance in the atmosphere and I was...
