I came across this condition purely by accident some three years ago when a patient of mine presented with combat related PTSD. In the assessment he reported that he had developed Misophonia during teenage years. I treatment him successfully for the PTSD using a therapy called EMDR. Part of the treatment involves the use of Bilateral music. He noticed that the intensity of the Misophonia reduced from 8/10 to an average 2/10. This is not a cure but it would appear that bilateral music helps to reduce the intensity of auditory irritation. I have since tried this with three other individuals (all referred for different mental heath issues) wth age ranges from 16-69 all who self report a reduction. I hope this helps.
