Do you feel like you are shivering when you hear the sound of a plate picking up a wire?

     Do you feel like you are shivering when you hear the sound of a plate picking up a wire? When a blackboard with nails scratches an umbrella, does a tooth set come to a sound? It's like reading something like this, and feeling like something's cool, right? There's a reason for that.

     There has been a lot of research over the years. Recording everything from scratch, rubbing two pieces of styrofoam, scratching a bottle with a knife, etc., are all recorded first. Then people take a sample and listen to them. Two of the hardest noises to come up with are the conclusions that come from scratching a blackboard with nails and writing with a piece of chalk.

     The next part of the research takes these two sounds and records each of them. Remove the harmonic pieces and change the frequency. We do this to find out what trigger frequency is. Then again, the new sound is made available to people. At the same time, their heart rate and preferences are similar to those of the whole body. And then you realize that the sound of people getting uncomfortable is not at the highest range we think. We're having a hard time getting anywhere between 2000 and 4,000 Hz. This is a low range, because a human ear can hear up to 20000 Hz. Macromedia in Germany has done one of its research in this regard. That's where this recital came from.

     Then, as part of this research, the choke sounds and the nails have a bit of a change in the frequency range, take another group and split it into two teams, let them listen to one team, and listen to it while the other sounds. We also take steps to ask whether these are pieces of a song. Then they look at their heart rate and pressure and see what happens. The know-how team is always triggered. But those who think that the sound is coming from a piece of music have listened to it anyway. But both of the teams reacted the same way. That is, when the noise comes to mind, it is difficult to listen.

     In 2012, a new journal, Science, published an article about how the brain works when it comes to hearing sounds. It reveals that the brain cells that cause our hearing and emotions are triggered by these sounds. Take thirteen and listen to seventy-four noises. Put that choking sound on his face and scream. An MRI scan of how the brain responds to those noises. It finds that when you hear difficult noises, there is a trade-off between the auditory cortex in the brain and the amygdala, which is weighted by emotion.

     Give us a voyeurism. It is a survival option given to the animal by nature. Often, this frequency comes from the screams of someone who has not heard a child cry or hurt. It's common to all animals. Then the creature becomes alate. Remember when the chimpanzee got upset? Warning that it is an accident gives the whole flock. When we were in Nuwara town (a town in Srilanka), our schools had a lot of trouble. When we are not in class, they are sophisticated enough to sip in the bag and eat out the food boxes. Suddenly you hear the sound of Kean Keung screaming from the range. We felt it when we were asked to count on the board and hand over the choke piece. But now that humans have come so far, animals do not need this animal option as much. But that setting is still coming to us, just like the bullet.
