There is a group of sounds that has no scientific explanation, many of these sounds are produced in many parts of the earth and others can travel thousands of kilometers and we still do not know what causes them, here I give you my top 5 most mysterious sounds of the land that are not explainable.
1. Upsweep
A sound recorded in the year 1991, from the sea, this sound has been produced several times since that year and scientists still can not explain what causes it, occurs in the months of April - May and October - November.
2. The whale of 52 hertz
This sound was discovered in 1992 and although you do not believe it is attributed to a whale never seen before, it is said that it could be the largest whale ever seen, scientists think it can be a whale since the sound is similar to others. that this one is emitted at 52 hertz when the others emit their sound between 10 and 39 hertz, the scientists argue that in order to emit this sound this whale must be 3 times bigger than a blue whale, and each year this sound is always repeat.
3. The Hum
This sound is a strange sound of very low frequency that has been heard throughout the world for more than 40 years, it is still listening, the people who hear them explain that the sound resembles the sound of the engine of a car ignited while at rest and that this sound becomes more intense at night. Experts argue that it can be a sound produced by the brain of some people since 2% of the world population can hear it.
4. Estallidos de Seneca
These sounds are more similar to outbursts that occur in the sky, the people who hear them argue that it sounds as if a military aircraft broke the sound barrier. These particular sounds are only given in Seneca, a city in Canada, but they still have no answers.... And they are very strong.
5. skyquakes
They are thought to occur in the earth's atmosphere and are heard hundreds of kilometers away, many people complain about this. Scientists have investigated and think that it may be changes that occur in the earth's magnetic field or that they may be sounds that occur before an earthquake occurs, since many of these sounds were heard before land occurred, of all forms are not known to produce them yet.
