Funny, I just heard a brief talk about misophonia on CBC the other day. A couple of the sounds leenia listed were given as examples of what were NOT misophonic - fingernails on a blackboard, squeaky brakes - because they are considered disturbing universally (there is some physics involved, which was kindly explained). It is when a person finds ordinary sounds such as the rustling of paper upsetting that you have a case of misophonia. As I understood it.
