MacPherson is interested as well in exploring whether the ultra-low sounds might emanate from the earth–be geologically rather than electronically driven. And he concedes, as well, the possibility that they emanate in some way from the human body itself.
For all mysteries, there are explanations that are more interesting, more creative, others that follow the straight line of Occam’s Razor. Which do you prefer for the Hum?
We truly doubt the “mating fish” hypothesis, and ones involving aliens–although Taos and the other centers of Hum-hearing are all attractive places to spend time on planet earth if you’re coming from a few million light years away.
Given how sensitive the sense of hearing in humans is, how frequency-based and yet unpredictable, there’s a lot to suggest the theories that focus on varying reactions to Ultra Low Frequency vibrations. Will enough testing prove that hypothesis? Stand by.
Remember that there’s more than one Hum, in other words there might be different science at play in different locations. Around northern New Mexico they”ll remind you how “extremely thin” the crust of the earth is there, and of the volcanic activity in local geological history. Other locations note how close they are to military installations that experiment with low frequency transmission to submarines and the like. It may well be the case that several Hums are heard around the world, driven by different vibrations.
And don’t forget, a social and psychological mystery lives inside the scientific one. Why do we assume that something we don’t experience, personally, doesn’t even really exist?
But can we assume that the power of imagination does not also figure into the experience of the “hearers?”
Is it science, or a mixture of science and psychology that produces what we call “The Taos Hum?”
Here’s a video for the specifically New Mexican phenomenon, and another that broadens it a bit:
