For the first time in half a century the strange sounds were recorded by scientists at the boundary of the stratosphere and space. The origin of the noise researchers have found is not yet possible. However, the striking intensity and complexity of infrasonic signals. Researchers are preparing for new experiments.

Strange sounds managed to fix with the help of equipment developed a graduate student at the University of North Korolina Daniel Bowman in one of the projects for NASA. During the experiment, special microphones picked up in the upper atmosphere at an inflated helium balloon. He rose to a height of 37.5 thous. M. This is much higher than the level at which planes fly, but at the same time below the point where the boundary lies between the open space and the upper layers of the stratosphere.

As a result, instruments caught whistles and hisses at a frequency below 20 Hz. To the human ear signals are indistinguishable, and recording with a special microphone has to accelerate to hear mysterious sounds.

"It is somewhat reminiscent of" The X-Files "- Bowman said, adding that he was shocked signal intensity and versatility.



The source of these strange sounds remains a mystery to scientists. In this respect there are a lot of guesswork and assumptions. For example. Some believe that it echoes the ocean waves, gravitational waves, air turbulence and turbulence, even laying on the cable of the helium balloon that lifted the recording equipment in the air. Natural phenomena such as storms and earthquakes, can also produce such sounds.

Despite the fact that the exact source of the low-frequency signal is not yet possible to establish the experiment is already recognized as a great success. For the first time in 50 years the acoustic recording was carried out in the stratosphere, says Bowman. Scientists are already preparing for the new experiment, to be held this summer.
