Why are some people irritated by screeching sounds like squeaky balloons?

[Mentallic]

What causes a good proportion of the human population (including myself) to be irritated by the sounds of 'screeching' elastics? Such as that of childrens' fingers rubbing against a balloon.
It seems that we are sorted into 2 categories, either you hate the sounds, or they don't bother you whatsoever. Children seem to be more resistant to the sounds as well. Does this have something to do with our ear structures, possibly as you grow older the inner ear changes in a way that makes you susceptible to falling into the 'hate it' category?

Overall, research shows that this ear-splitting noise has the same frequency as that of a crying baby and a human scream, indicating that these sounds are tied to survival. For instance, people attuned to these frequencies may rescue a crying infant sooner, improving the baby's longevity.
