You should get a workup by an ENT, preferably one that specialized in Tinnitus from large university that does research and trials.
There could be many reasons causing tinnitus from a vessel contacting your auditory nerve / ear drum or loss of hearing in a certain frequency. Pulsatile tinnitus from vascular contact can be treated with surgery and hearing loss based can be easily treated with hearing aids that amplify the hearing loss in the diminished spectrum.
The auditory center of the brain, for some reason, replaces the loss of hearing with it's own sound, i.e. tinnitus.
When you restore hearing in that range, the brain might stop the hearing loss, it can take a few days but I know people who have had success with this treatment. Some hearing aids also provide masking sounds.
New treatments are coming, some focusing on the nerves in the brain that are disrupted by electrodes on the head / neck or even with the occasional use of an electrode under the tongue.
Millions of Americans hear ringing in their ears—a condition called tinnitus—and new research shows an experimental device could help quiet the phantom sounds by targeting unruly nerve activity in the brain.

In the largest clinical trial of its kind, researchers show that combining sound and electrical stimulation of the tongue can significantly reduce tinnitus, commonly described as “ringing in the ears.” They also found that therapeutic effects can be sustained for up to 12 months post-treatment.

BTW, Costco is the best place to go for hearing aides. Mom and pop shops, from what I hear, will sell overpriced units and have the same training as Costco employee, which is an AuD (Doctor of Audiology). The aides are top of the line as well.
