This is a topic which should be covered by audiologists, not cognitive psychologists. In fact, I'm pretty sure there's some previous literature about this topic. Where is the discussion on the physics of audio, the chords harmonically generated by instruments, and their effects within the ear? These aren't just chords which "sound unpleasant", there's an actual physical way to describe this. Is this study just more scientific noise?
