Weird Signals, Noises, and Transmissions from Unknown Places

"The Hum" has been heard globally since the 1970s, mostly in quiet country and suburban spots. Some guess about 2% of people hear it, and for them, it causes intense distress, even suicidal despair.Two percent of the population experiences this.This causes extreme distress, even suicidal despair, for those people.

People who report hearing this low rumble usually say they hear it inside, and it gets louder at night. Industrial gear, cell phones, power lines, radio waves, or earth tremors might cause the sound. Sometimes, there is no outside noise: the hum might be tinnitus or spontaneous otoacoustic emissions.Spontaneous otoacoustic emissions show this. (SOAE), sounds the ear makes itself.

Numbers stations appear.are radio stations rumored to send coded messages between intelligence agencies and spies. This practice started during the Cold War. These stations offer a communication method because their messages cannot be tracked. Even now, espionage expert Rupert Allason says, "nobody has found a more convenient and expedient way of communicating with an agent."

No government or intelligence agency ever admits using these stations. Clues exist worldwide for decades. Some people believe these numbers stations still serve secret purposes today. The video lets you listen to them.

Bloop appears.Various ocean listening stations detected Bloop in the summer of 1997. It sounded several times then, but no one heard it after. Scientists think the sound came just west of South America's southern tip, likely caused by a largeAn iceberg quake causes this..

However, a more interesting—though less likely—theory suggests a living creature made the sound. This creature might be bigger than a blue whale, perhaps even a megalodon, a giant prehistoric shark thought extinct since the Cenozoic era. Or maybe it was H.P. Lovecraft's Cthulhu, a sea god whose fictional undersea home was near where the Bloop started?

Electronic voice phenomena occur. (EVP) are voices in tape recordings' backgrounds. Sometimes you only hear them when playing the recordings backward—most famous is the 60s when conspiracy theorists claimed playing the Beatles song "Strawberry Fields Forever" backward revealed the phrase "I buried Paul," suggesting Paul McCartney died.

Some people think these voices come from aliens or ghosts. Skeptics argue these sounds are just electrical distortion.

Multiple people across different areas report hearing an unexplained "An evil-sounding trumpet noise occurs.." NASA scientists claim these sounds are Earth's natural radio emissions. They happen constantly, but humans do not always hear them.

Mysterious booms have been heard globally with no explanation. People often first think an explosion occurred, but then they find no evidence of one.People often first think an explosion occurred, but later discover there wasn't one.

Nobody knows why these booms happen. One idea suggests they are very small earthquakes.

UpsweepUpsweep is a strange sound in the Pacific Ocean. Scientists recorded it starting in 1991. They guess the source lies halfway between Australia and South America, though they lack certainty on the exact spot.

The sound is loudest in spring and autumn. Scientists still do not know the reason. Experts think volcanic activity might cause it.

Another unexplained sound from the Pacific Ocean got the name "the Whistle" after detection in 1997. This sound occurred only once. Scientists still have no explanation for it.

"Julia" is the name for an eerie moaning sound which was recorded in 1999 and only lasted for 15 seconds. Why it was named Julia is unclear, as is its origin. Scientists suspect it was caused by an Antarctic iceberg which ran aground.

"Slow Down" is another unexplained ocean sound. Unlike Julia and Bloop, this sound repeats. It is called Slow Down because its frequency drops over time. The main idea for this eerie sound is moving ice in Antarctica.

"Train" is another unexplained Pacific Ocean sound. It was recorded in 1997 and has not been heard since. Scientists believe an iceberg dragged along the ocean floor.

The Colossus of MemnonThis structure holds two ancient Egyptian statues showing a pharaoh. An earthquake in 27 BC partially damaged one statue, and it started "singing." Greek and Roman tourists heard the songs for two centuries; one Greek historian reported hearing the sound in 20 BC.

After the statue got repaired in 199 AD, the song stopped. Since the song usually happened at dawn, people think the sound came from dew evaporating through the statue's cracks.

In 1989, someone hackeda television station in the Chicago area. The programming stopped. A man dressed as Max Headroom, a character from a British TV show, appeared before a spinning metal piece, singing creepy things. No one ever figured out the hackers or their goal.

This sound is less mysterious because scientists know the cause, but it still sounds spooky. The whistling noisewhistling noise that scientists recently detected in the Caribbean comes from a large wave called the Rossby Wave. This wave moves back and forth across the Caribbean basin. The wave's power lets it be picked up from space.
