10 Most Mysterious Noises Ever Recorded

Without audition, we’d miss out on some of life’s pleasantries – birds chirping, soothing music, the sound of the sea; but most of all, you wouldn’t be able to experience these recorded noises which are so mysterious that their origins remain officially unidentified.

SPOILER ALERT!!! A condensed list is below:
➢10. The Whistle
This single frequency signal was picked up by the National Oceanic and Atmospheric Administration, an American agency which is also known as NOAA. On July 7th, 1997 it recorded this noise which has similar characteristics to wind howling at night. Credit:
➢9. The Bloop
This ultra-low-frequency and extremely powerful underwater sound was also recorded by NOAA several times and was roughly triangulated to a remote point in the south Pacific Ocean west of the southern tip of South America. Credit:
➢8. WKCR 89.9 New York’s Old Tape
WKCR is a fairly familiar radio station to those around Columbia University, but one night in 1995, the station allegedly veered off its usual course to play this strange series of haunting music, horrific whispers, and a synthetic female voice reciting dates and names. Credit:
➢7. 52-Hertz Whale
When first recorded by a US Navy sound surveillance system in 1989, scientists were quick to associate this underwater recording to the call of a whale, but that didn’t end the mystery behind this 52-Hertz sound. Credit:
➢6. The Lincolnshire Poacher
For around 30 years, a radio transmission of the English folk song, The Lincolnshire Poacher, played repeatedly, followed by a series of seemingly random numbers. Credit:
➢5. A Phantom Cosmonaut
What we're about to play is a haunting transmission of an alleged lost Soviet astronaut that was intercepted by amateur radio operators in 1961. Here is that audio, which is believed to document the final moments of an unknown female cosmonaut entering Earth’s orbit. Credit:
➢4. Julia
Like an underwater EVP, the NOAA’s March 1st, 1999 recording dubbed “Julia” is an eerie, unexpected groaning that sounds incredibly unnatural for the environment it was captured in. Listen and let us know what you think. Credit:
➢3. Upsweep
In 1991, scientists stumbled across what the NOAA describes as a “train of narrow-band upsweeping sounds,” hence the name. The noise was detected throughout the Pacific Ocean, making it difficult to localize the noise. Credit:
➢2. UVB-76 – The Buzzer
Mysterious radio transmissions have been captured time and time again, but the 4625 kHz shortwave buzzing of the UVB-76 radio station has been ongoing since 1973, occasionally sending out a string of dates and names spoken in Russian. Credit:
➢1. Earth’s Trumpets and Skyquakes
You’re enjoying the fresh air outside when suddenly one of these thunderous, unnatural sounding trumpets blare through the sky. Despite having been heard across the United States, United Kingdom, Canada, Australia, and Germany, scientists at the National Aeronautics and Space Administration remain baffled by the cause, claiming that it could just be The “background noise” of Earth .
