Tinnitus is not caused by hearing loss, although it is associated with hearing loss. Get your hearing tested and see what you find.
I agree with Wear/a/Jimmy that you need a hearing test (audiometry).
These guys are right, you need a hearing test. The only problem is whether or not the result is negative or positive you only have a reason, not a solution. Tinnitus bothers different people at varying degrees. It's important to learn all you can about this. See some of my other posts.
