I am very sensitive to sound as well. Hyper-sensitive is actually what the doctor in Audiology dx'd me with. It is hyperacusis. I need to gently ease my ears into "normal" sound levels through ear exercises. She highly discouraged me from wearing earphones or earbuds all of the time, as it will only make my sensitivity stronger. *sigh*
