I do not think they will make your tinnitus worse. Maybe you will be more aware of it for the time being but it is temporary. You are still very much in the early stages of your tinnitus. When my tinnitus was as "young" as yours i was very bothered by it and i couldn't concentrate. I was of course very upset by this.
Now, in spite of the loud noise not only do i sleep like a baby in silence but i can study math in a calm place without problem.
So if you ever have concentration trouble or panic attacks don't worry too much about it: it will pass. I've been there and it passed.
