That sound isn't from Star Trek. It's an audio clip created from radiation coming 100,000 miles above Earth's surface. These waves are thought to be created from bunched up, charged electrons trapped in Earth's magnetic field. These rising and lowering waves of radiation have been studied for the past 70 years.

And a new study from Beijing, China, published in the journal Nature, was the first to find these waves at this location, where Earth's magnetic field is weak and less uniform. This information could help protect satellites and other spacecraft from damage, since chorus waves can accelerate particles to close to the speed of light. Regina Barber, NPR News.
