Slow Down

On May 19, 1997, the US National Oceanic and Atmospheric Administration (NOAA) discovered a strange sound in the Pacific equator thanks to an underwater sound sensor.

Its sound frequency decreases with a 7-minute cycle so it is called "Slow Down" by scientists. But they still have not identified its source.

Some researchers hypothesize that this is the Arctic sound of ice moving slowly but they do not have enough evidence to draw conclusions.

Quacker - Duck sounds

"Quacker" is the name given to scientists by a strange sound similar to the sound of a frog flooded. It was installed in the Arctic and Atlantic Ocean by high-tech equipment that received signals from the Soviet ocean during the Cold War.

Quacker has a speed of up to 200 km / h, it automatically avoids ultrasonic waves and submarines. There are many hypotheses to explain the origin of Quacker, such as the sound of secret military technologies, the sound of hidden submarines, the sounds of aliens or of marine creatures. strange somehow. But no one gave a reasonable explanation to Quacker.

EVP - The sound of the soul

EVP is an electronic voice phenomenon, recording sounds and voices of the mental world. When rewinding many rewinds of audio tapes, digital recorders or videos, researchers on the phenomenon of mystery suggest that they have discovered strange conversations.

EVP can be just a word, phrase, sentence or even conversation. Many people believe that it is the voice of the souls. But others think that this is only a natural noise phenomenon.

The pareidolia hypothesis (complementary illusion), EVP is born from the human brain trying to turn meaningless sounds into meaning. According to the apophenia hypothesis, the EVP comes from human imagination.

Sound of the planet

As we know, in the universe is a vacuum environment so the sound cannot be transmitted through planets. But radio waves can travel in space so that spacecraft can send information to Earth. Researchers have discovered some strange sounds mixed into it.

Many people believe that the moon and planets emit sounds similar to howling or whistling. Recording devices on the spacecraft record and turn into sound waves that can be heard. Those are hypotheses, not concrete evidence, so these sounds are still a mystery.

Mistpouffer

Strange and random sounds like thunder from the big waters like the Yellow River in India, the Great Lakes (Great Lakes) in North America without storm are collectively referred to as Mistpouffer.

Mistpouffer can create shock waves, when people are still miles away. A series of Mistpouffer's origins hypotheses have been proposed by scientists as compressed air, falling meteorites, collapsed underwater caves or by rapid air pressure but they have yet to find an explanation. well suited.

Mysterious howls

Strange howls have been recorded in the town of Pass, Manitoba province. Nobody determines what sound it is and why it appears. A series of different opinions are given, such as music, howls from the Earth, even the sound of hell . controversial.

In some other cities such as Glasgow (Scotland), Chicago (USA) and Denmark, people also recorded similar howls.

Mysterious sounds in the One World Trade Center

Residents of the area near the One World Trade Center were amazed to hear sounds like sad humming or faint cries emanating from buildings in the area while walking.

This strange sound was discovered for the first time in Hurricane Sandy, 2012. Initially, they thought it was the sound of a vacuum in unfinished buildings. But after the storm and even when the buildings were finished, these mysterious sounds were still heard. Many people believe this is the voice of the dead soul.

The buzzing

Mysterious buzzing sounds appear around the world but not everyone hears. Many people believe that this is noise and earplugs but not effective. Until now, science has yet to explain its origin.

The buzzing sounds often appear at night and go through the body like vibrations making it harder for science to give an explanation.

Bloop

In 1997, the US National Oceanic and Atmospheric Administration discovered low-frequency sounds emanating from a depth of about 4,300 meters in waters about 1,750 kilometers west of Chile. This sound has a high amplitude, the sensors can recognize it within 5,000 km and are called Bloop.

Bloop has a similarity to the sounds of marine animals, but no species on the ocean floor can emit such loud sounds including blue whales. Researchers believe that Bloop comes from cracks of large ice sheets on the ocean floor.

Wow signal

On August 15, 1977, when searching for extraterrestrial life, Dr. Jerry Ehman discovered Wow signal. This signal appears only once and lasts 1 minute 12 seconds. When studying carefully the graph of the intensity variation of the signal, Ehman denied his original hypothesis that Wow is an earth signal that responds to debris in the universe.
