Short answer: Get an evaluation by an audiologist, if possible, to determine if something can be done.

Long answer: Depending on the personal cause of tinnitus, solutions range from nothing to getting hearing aids with specific software that provides tinnitus relief. I have genetic, moderate to severe hearing loss in higher frequencies and have very noticeable tinnitus. The complications from hearing loss with tinnitus can vary, but personally were resulting in increased sensitivity to noise throughout the day, irritability, and diminished ability to communicate (I couldn't hear what my spouse or kids were saying when there was any kind of background noise present). It led me to never want to go anywhere or do anything outside our home because I couldn't hear or enjoy anything.

I went to an audiologist, had a bunch of tests, and was prescribed a set of hearing aids. Said hearing aids play soft ocean noises in addition to boosting the frequencies I have diminished hearing in. The ocean noises allow the brain to train itself to treat the tinnitus as a routine background noise instead of a panic inducing "danger" sound. Over time, it has helped in significantly reducing my attention to the tinnitus. It will never go away, and I have to sleep with ocean sounds playing so I don't go insane.
