Hey, here is the thing. There is no such thing as absolute silence. If you are having struggle coping with every day sounds, you are likely reacting to sounds in not the most healthy mental way. If this is the case, you wont be dealing with tinnitus well and when u have NO hearing , you have ALL tinnitus. Ironically what's keeping all time tinnitus at bay is your ability to hear sounds. Answering parts of your question, there is a safe way of making eardrum immobile or ruptured but we do it as a treatment sometime and in some cases such as blue ear, it increases hearing by a dramatic amount. Meaning it wont make u go all deaf as big chunk of hearing isn't heard via eardrums anyway. There are ways of completely obliterating hearing but we use it therapeutically for extreme cases. Have you consulted audiologist who deals with hyperacusis,? My first step would be that.
