We all know that feeling. You’re trying to concentrate on work, or maybe you’re trying to read, and then it happens: that high-pitched, nails-on-a-chalkboard sound that just makes you want to scream. It’s the sound of someone eating rice crunching, or maybe the sound of a fork scraping against a plate. It’s a sound that’s so annoying, it’s been used in scientific studies to study pain tolerance.

But why is this sound so annoying? It turns out, it’s all about evolution.

The world’s most annoying sound is actually a frequency that’s right around 2,000 Hz. And that just happens to be the frequency that’s most effective at causing pain in humans.

In fact, this sound is so effective at causing pain, that it’s been used in military sonar systems to disorient and disable enemy soldiers.

So, why is this sound so effective at causing pain?

It turns out, it’s all about evolution.

Our ancestors lived in a world full of predators, and the ones that could best avoid getting eaten were the ones that could hear these high-pitched sounds.

As a result, our brains have evolved to be sensitive to these sounds, and when we hear them, it triggers a stress response.

So, the next time you hear that sound, just remember, it’s just your brain trying to keep you safe from getting eaten by a saber-toothed tiger.
