Oops, I misunderstood. I thought you got an additional tone on top of the one(s) you have. If your tinnitus is still so new and because of an acoustic trauma you should try to get your GP or ENT to prescribe you some Prednison, if you haven't tried that already.
And try to give yourself and you ear as much rest as possible. Which I know is hard when suddenly there is this intrusive noise in your head. If the noise can be masked, mask. Anything to not make this new noise the sole focus of your life. Best of luck!
Ive had tinnitus 8 years .. 2 weeks ago i panic cause i was muffled in the bad ear and slight more ring i got on prednisone and ended up listening to a app for tones and it left massive ring in each ear even one i thought had no tinnitus i was in panic doctor said stop the prednisone its driving you mad .
