Top 10 sounds make people feel afraid

Scientists have seriously studied to find out what sounds cause the most discomfort for humans. They find that sounds are capable of making us 'unbearable' often high-frequency or related to the gastrointestinal tract.

1. Vomiting

Vomiting does not make us feel uncomfortable because of its sound, but an image of association in the brain and causes some reactions in the body. Some people said they could not bear it, even nausea when they heard this sound.

2. The sound of the microphone

Many of you must have heard this annoying language in karaoke rooms or on some big stages. This sound is generated by the feedback from the loudspeaker being transmitted directly or indirectly to the microphone and when these frequencies overlap it produces a very high frequency sound.

3. The sound of children crying

Physics professor Brian Cox conducted an experiment involving annoying sounds. The results are quite surprising when the sound of children crying is also listed, especially for men. Professor said that this sound not only affects hearing, but it also feels tired and troublesome, because normally when children cry, adults must be tired to comfort.

4. Voice of trains running on rails

Even if you do not live in a place where frequent trains pass by, similar sounds when metal comes in contact and collides with metal always cause discomfort.

5. Metal rust

Things like a swing, door hinges or some rusty metal objects when the movement makes sounds can make you feel cold. This sound is not only annoying because of the high frequency, but also makes the mind relate to horror.

6. The sound of chewing food

The researchers were also quite surprised when the sound of food chewing was also included in the list of sounds that make people feel the most uncomfortable. These people said they could not bear the reputation of chewing other people's food while in a restaurant or in the cinema.

Even if you are not eating, the 'copy' when someone chews food that opens your mouth will make you uncomfortable.

7. Voice claw nails on the blackboard

This is a sound that is considered extremely annoying, because of the screeching sounds it causes. Not surprisingly, this sound was voted by many to be the most annoying sound.

Today many places use whiteboards instead of blackboards, so if you can't hear this creepy sound again, you can try it here.

8. Voice of dentist drilling machine

If you've ever been to a dentist, you've probably had the opportunity to hear the sore sound to this bone. Professor Cox said the dentist's reputation for drilling with high frequency elements and affecting our minds to think about pain.

9. The sound of a sharpening knife on glass

Scientists at Newcastle University conducted a study, which focused on the sounds in the frequency range from 2,000 to 5,000 Hz. There was a sound of sharpening knives on glass bottles, clawing nails on the blackboard and metal clashing. As a result, the sound of knife sharpening on glass causes the most inhibition in the brain, according to the results of an MRI machine.

You can go to the kitchen and try to create this sound with a knife and a glass bottle.

10. Car horn in Vietnam

In many developing countries like Vietnam, the situation of honking car horns when participating in traffic is not a rare thing. Especially at rush hour and road work. Researchers say the current situation of car horn may cause noise pollution in developing cities.

Other studies have also demonstrated that the sudden appearance of car horns with maximum volume also has a strong impact on the nervous system, there have been cases where motorcyclists have heard the car horns startled and lead cars. to death.
