Annoying sound files

The researchers found that the amygdala interacted with signals coming from the auditory cortex, increasing the amount of unpleasantness conveyed by sounds at the top of the list, which all happen to occur in the frequency range between 2, and 5, Hz. Brain activity in the amygdala increased for unpleasant sounds.

Previously, scientists have speculated that we might found these sorts of high-pitched sounds so irritating because they acoustically resemble the alarm calls of our primate relatives, such as chimpanzees. At some point in our evolutionary history, the theory goes, we evolved the innate tendency to find these alarm calls emotionally terrifying so that we would be more likely to act upon them and avoid predators.

Theoretically, this tendency might have stuck, despite the fact that fingernails scratching on a chalkboard have nothing to do with actual predators. More recent research, though, makes this theory seem a bit less likely.

An entirely separate hypothesis is much simpler: that the actual shape of the human ear happens to amplify certain frequencies to a degree that they trigger physical pain. A cicada flew in my front door a few weeks ago and so i grabbed it and kept moving him around just inches from the mic trying to make him make some noises. This is just one of them.

My brother used to have a phone and he broke it. So I recorded it. This is all it did when you turned it on. Some rich valley girl saying totally. A very valley girl thing to say.
