I don´t wear my aids in the night. I think there are some people who wear their tinnitus-maskers in the night.
With hearing aids, you can do the following:
- hope that the tinnitus will get less if you wear them. This effect is persistent in a way that the tinnitus is also less when you don´t wear them
- use a tinnitus-masker (there are different ones, I think widex is the company with the most experience in this field)
I read an article about that: The human ear and brain is not made for complete silence. Thousands of years ago, when people were sleeping in the wild, there was always some rustling, animals and so on. No complete silence, never. If you encounter complete silence, the brain is making off some noise - there you have your tinnitus.
With my hearing aids, I hear the fan of my pc, the clock ticking, my clothes rustling and so on, even if it´s quite silent. Also I don´t have to strain myself to understand people. That´s what I think is why my tinnitus got better with hearing aids.
As for gene therapy, the scientific papers reported some progress in making nerves sensitive to light. This way you can implant a much finer grained cochlear implant that emits light, not electric stimuli.
In my opinion, gene therapy is still very experimental and very risky. I´d consider it only if it´s a matter of life or death.
Is your tinnitus worse after gigs? If so, maybe the ear protection is not as good as you think. Also, you cannot protect yourself from very low sounds, because they come in through the bones.
Here in germany we have a professor for music-related illnesses, maybe you find something like this in your country. Also it would be a good idea if you find the exact amount of your hearing loss.
