@mapman The Fourier series theory stands behind all of electromagnetism.
The em wave emitted eventually by way of speaker transducer, becomes a sound wave. The cart before the horse scenario. The reason the Schumann frequency affects you, and all human physiology is because the frequency induces a calming, relaxed, yet alert and focused influence.
It is a theta frequency (7-12 Hz).
The idea has nothing to do with sound.
IT has everything to do with the manipulation of e signals that become sound waves.
That's what amps and speakers do.
There is no rational explanation out there that connects the dots.
Again: square wave, Fourier harmonic series, and resonance. All supported by laws of physics, which includes the science of sound. Get it?
