I’ve had pretty bad (self induced) Tinnitus for many years. It is over several frequencies from around 1k upwards. Hearing tests become very tricky as there’s so many sounds already there. 
Hearing aids give me tremendous relief, as now those frequencies contain other noises. The Tinnitus is still there, but I rarely notice it. My HAs have a Tinnitus masking programme. I tried it, but it just added more unwanted noise. My wife could hear it across the room!
Now, Hearing Aids work for me, but my loss is substantial. With your loss, it might not be so beneficial, especially in your good ear. Might be worth giving them a try?
Good luck
Peter
