Lightning-made Waves In Earth's Atmosphere Leak Into Space

TheNextCorner sends this quote from NASA: "At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth, captured between Earth's surface and a boundary about 60 miles up. Some of the waves – if they have just the right wavelength – combine, increasing in strength, to create a repeating atmospheric heartbeat known as Schumann resonance. ... NASA's Vector Electric Field Instrument aboard the U.S. Air Force's Communications/Navigation Outage Forecast System satellite has detected Schumann resonance from space. This comes as a surprise, since current models of Schumann resonance predict these waves should be caged at lower altitude, between the ground and a layer of Earth's atmosphere called the ionosphere."

    33.8Hz can be picked up with the human ear. Mad Bass.

    To add, 33.8 is a slightly sharp C1. It's about halfway between C1 and C#1 on the musical frequency scale.

    how far away is this detectable? this may be how you find other earth-like blue orbs

    until of course, they find the liquid ammonia planet that schumann resonates like nobody's business, populated by little mr. cleans and scrubbing bubbles i suppose

    My guess is, that since it's eletromagentic, it follows the inverse-square law.

    It can't pick up these waves, because the human ear picks up sound, not magnetic waves. There are some bones in your sinuses that are magnetoceptic, but studies have yet to get detailed. It's such a rudimentary sense that you are barely able to pick up the magnetic north with it, so it's highly questionable that you'd be able to pick up rapidly alternating differences in magnetic fields.

    It is however proven that these magnetoceptic bones are a real human sense. So yes, there's at least a sixth sense there. Oh, for that matter, totally off topic, your balance sense (inner ear) also counts, so make that a seventh, or an eighth, if you count the receptors for pheromones in your nasal cavity as well (debatable, since it's a form of smell, just not consciously perceived).

      Your ears may not be able to detect these, but your computer's soundcard can. It can also detect all sorts of other ELF transmissions. Check out http://www.vlf.it/ - fascinating stuff!

    Electromagnetic pulses from Jupiter can be detected in the Amateur 15 Meter Band, approx 21 Mcs (No damn hertz for me. That's a car rental company. Been banging out CW since I wuz a kid, and I ain't a kid no more.)
