Random Knowledge 6: Infrasound -vww

Infrasound, as one might have guessed, is the term for sound that is below the human audible frequency range. There are various natural phenomena that can produce infrasound, e.g. earthquakes, aurora, etc. And it is not surprising that many animals are capable of detecting infrasound. But what I find particularly interesting is the effect infrasound has on humans.

Studies have shown that certain infrasonic waves can cause anxiety and discomfort in humans. Some researchers suggest that naturally occurring infrasound causes people to attribute their experience to ghosts.

Yes, there is this type of infrasound called "Brown Noise" which induces humans to empty their bowels uncontrollably. Think of all the cool stuff you could do with that.
