My auditory turn-offs are sounds intent on evoking chaos and cacophony (old Bruce Springsteen music, inside of any casino), expressed grandiosity (nearly all 'show tunes', wailing mourners and crying babies, etc.), deliberately manipulative sounds (unwanted sales pitches, movies that go real quit so you can't hear the dialogue, and then blast some sudden noise real loud to 'scare' the audience), and inarticulate sounds (songs and movies with mumbled and unclear dialogue, or dialogue so confusedly written or delivered that it's unintelligible. Public speaking of the same ilk.
