Why does a fork scratching a plate bother me?

A 2011 study by musicologists Michael Oehler and Christoph Reuter led its authors to hypothesize that the unpleasantness of this sound is caused by acoustic resonance due to the shape of the human ear canal which amplifies certain frequencies, especially those in the range of 2000 to 4000 Hz (the median pitches …
