i hold a category 1 medical, i am partially death in my left ear (50%), right ear is great. i am restricted to earphones. which is not a problem haha. i also had to go up with an examiner and he tested whether i could hear instructions, i was aloud to turn them up as loud as i want. there are also other ways of getting a letter of recommendation from an instructor, stating that you are able to hear and understand things under the circumstances. there are ways around it. one of the main side effects of being a pilot is hearing loss. there are also noise reducing head sets well all of them do that haha. hope that helped.
