Sounds like the earth's atmosphere?

What kind of noises does the earth's atmosphere? Very, very strange. Acoustic signals recorded in the stratosphere at altitude of 35.4 km, as if taken from the series "Secret materials".

These so-called infrasound very low frequency — less than 20 Hz and under normal conditions is inaudible to the human ear. Using 1000-fold speed, scientists were able to translate them distinguishable for people signals.

It is believed that the sounds in the atmosphere — a combination of events that took place away from the balloon (hood commercial aircraft, the roar of the waves in the Atlantic ocean, air turbulence, even the work of air-conditioning in buildings) and events happening nearby (vibration of wires on a ball, the impact of cosmic rays on the sensor).

Scientists believe that the signals cannot be a sign of extraterrestrial life. Sound can't travel through space, so its source had to be located at a distance of 140 km from the surface of the Earth.
