the authors suggest there observation of a group of  Misophonics showing enhanced sensitivity to higher frequency tones might be the result of neurophysiological adaptation, producing enhanced perceptual acuity  toward specific sounds  (specifically  in high frequency range). they go on to suggest that these perceptual changes might be driven by cog/neural processes preferentially amplifying certain auditory  stim, which enhances the Misophonic response.

• this implies that 1) all trigger sounds are in the high freqs range , and 2)  amplification of sounds happens at a point in the processing where source identification has occurred ( otherwise how could it have a preference? )
• these are both testable predictions that could be the bases of a future RQ. (page 5)
