I wouldn't be so quick to dismiss this.
Schumann Resonance is a real thing, and there isn't a lot of research into the audible effects of electromagnetic ELF and its impact on human sensory systems. After all, the side effects of alternating ionic fields of ELF on subconscious processes is well known by now. The question is, how do these effects manifest in subspace frequencies? There is doubtlessly a relationship there, but the exact nature is difficult to establish with current technology. If we could somehow use an inverted pulse interference, we could map out these disturbances, and the greater effects of the phenomena would be better known. It would not need to be a large project- all we have to do is modify the deflector dish to emit an oscillating plasma variance at relativistic phase angles, and then measure the difference of the Schumann Resonator in our reference audio system. It's quite simple, really.
