2. Microphone response sound

Extremely bright microphone feedback often appears in karaoke rooms or on some large stages. The cause of this sound is because the feedback from the speaker is transmitted directly or indirectly to the microphone, and when these frequencies overlap, a very high frequency sound is produced.

3. The sound of children crying

The sound of a baby crying is also one of the most annoying sounds for humans, especially for men. The reason is that this sound not only affects hearing, but it also creates a feeling of fatigue and trouble because of having to comfort the baby.

4. The sound of trains running on the tracks

The sound of trains running on rails or the sounds of metal contacting and colliding with metal always cause discomfort to listeners.

5. The sound of metal rusting

The sound made when some rusty metal objects move like a swing, door hinge… can send chills down your spine. The high frequency sound is annoying to the listener. In addition, it also makes many people think of horror movies.

6. The sound of chewing food

Many people feel uncomfortable when they hear the sound of chewing food, the 'clicking' of others when in a restaurant or in a movie theater.

7. The sound of nails scratching on the blackboard

Fingernails scratching on the blackboard create a shrill, agonizing squeak that makes listeners extremely uncomfortable.

8. The sound of the dentist's drill

The sound of a dentist's drill is both high-frequency and causes our brains to think about pain. Surely no one wants to hear this bone-aching sound.

9. The sound of knives sharpening on glass

According to research by scientists at Newcastle University, the sound of sharpening knives on glass causes the most inhibition in the brain.

10. Car horns in Vietnam

In Vietnam and many other developing countries, honking car horns indiscriminately when participating in traffic happens quite often, especially during rush hour and traffic jams. The honking of a car horn not only causes noise pollution, but also has a strong impact on the nervous system if it appears suddenly at maximum volume. There have even been cases where motorcyclists heard the horn of a car and were startled to fall over and lead to an unfortunate accident.
