Some sounds that I hate. The sound of Styrofoam. The squeak of bad car breaks. What makes us hate certain sounds? Like nails scratching the chalkboard or squeaky shopping carts. Just imagining the sounds are making my hairs stand up! (On another note, why do our hair stand up? How about goosebumps? Adrenaline.)
(Hairs are standing...)
Is it certain frequencies that our ears hate? It's can't just be high frequencies because people enjoy the sounds of birds chirping in morning (anything other time is a toss up). Is it possible that our ears aren't accustom to the unnatural noises mentioned previously? And we develop a comfortable set of frequencies while living our lives. Similar to why some people don't like their own voices, we don't like certain sounds because they are so foreign.
Just like taste, people tend to have different "tastes" in sound. But is there a noise that everyone hates? Misophonia. It's interesting because the reason we may hate the nail on the chalkboard sound because it's in the frequency range that the shape of the human ear amplifies most (becoming more sensitive to).
Would you choose to listen to nails on a chalkboard for 12 hours or complete silence for 24 hours?
