hi mate, as a tinnitus sufferer I fully understand how your feeling. I still hold my class 1 medical without any restrictions. yes, if yoyr tinnitus is permanent you will suffer some hearing loss but it should only be in thehigh range of frequencies and therefore have no effect on you day to day. a chat with an aviation medical examiner will help put you at ease.
I assume you understand what happens in your ears to cause tinnitus, I hate to say it but its generally going to be permanent and all you can do is just get used to it.
