Why Fingernails On a Chalkboard Sound Painful 176
sciencehabit writes "Some sounds are excruciating. Take fingernails squeaking on a chalkboard. The noise makes many people shudder, but researchers never knew exactly why. A new study finds that there are two factors at work: the knowledge of where the sound is coming from and the unfortunate design of our ear canals. 'The offending frequencies were in the range of 2000 to 4000 Hz. Removing those made the sounds much easier to listen to. Deleting the tonal parts of the sound entirely also made listeners perceive the sound as more pleasant, whereas removing other frequencies or the noisy, scraping parts of the sound made little difference.'"

Dammit no. I remember being a child and hearing that sound and cringing then finding out AFTER that I wasn't alone.
Some things just plain old suck (like fingernails on a chalkboard and communism).

They've only narrowed down the class of sounds, but not why we would find those sounds so annoying.
Re:My wife's voice (Score:5, Insightful)
It appears that AC is married to someone with a harsh voice. The AC didn't claim that all women, or even all wives, have harsh voices. AC just claimed one person who AC likely spends a lot of time with has a harsh voice.
Although AC could have said "$WIFE_NAME's voice is the only sound more harsh...", that would not have conveyed that AC likely spent a lot of time with that person. For example, if AC had said "Jane's voice is the only sound more harsh...", for all we know 'Jane' could be a checker at the local Walmart and since, presumably, AC doesn't spend that much time with a particular checker at Walmart, the message would have reduced significance.
AC could have used the word spouse instead, but that's rather unnatural and unusual as most people refer to their 'wife' or 'husband' rather than their 'spouse' in normal conversation.
