- 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'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 wondering if I could capture or concentrate those sound waves on an energy harvesting system via triboelectricity or piezoelectricity. If anyone could help me, I would really appreciate it.
