Feels a little reassuring seeing others in the field posting about tinnitus and worse hearing at __ frequency in one ear etc.
What I will say about tinnitus, based on the great ENT specialists I saw recently, is to try not to let yourself get too bummed out about a few things: a) you will hear from lots of 'professionals' that it is permanent in most cases, and there's nothing to do but learn to live with it - that is not true, and knowing this can help you come to terms with it; b) a lot of the longevity of the annoyance caused by tinnitus (and thus, the tinnitus itself) is because of the emotional attachment placed on the noise by us, as musicians, blaming ourselves for the noise and feeling guilty. Guilt in particular is a very strong emotion, and feeling this when you hear your tinnitus can embed the sound further and encourage your auditory system to listen out for it more because the noise is perceived as a threat; c) lots of people get tinnitus, but (according to the info I was given) 85+% do not 'suffer' to a high level and this is mostly because of their mental makeup - they tend to be people who worry less, in general, so when they hear the noise they are less likely to let it become an annoyance through concern over the noise.
Basically, I've found I'm coping better and better by doing what I can to believe in the power of the mind to overcome this - afterall, when you walk into a kitchen and the refridgerator and freezer are making a loud humming noise, you may hear it at first but because of the lack of importance attached to the noise you will soon forget about it and stop hearing it. Tinnitus can be treated the same way, over time, with habituation/tinnitus retraining therapy, and once your mind has learnt to switch the tinnitus out of the soundscape it focuses on, you can effectively go back to living without annoyance.
Some of the above is my own experience, and some what I hope to experience based on the research I've read recently, but I do believe that until they find a physical cure, the best treatment is through willpower and mental training. If you're having trouble sleeping at night, try and create a long CD with sounds that are in the frequency areas of your T so it will mask it a bit. From what I've read, you will find fastest results at habituation if you don't completely mask the tinnitus, but get the CD to a level where you can hear the tinnitus if you listen out for it, but as you get drowsy and focus on the CD you will train your mind to focus on other sounds. It is unnatural to sleep in environments as quiet as we do nowadays, with our soundproofed homes, so to some extent natural soundscapes work best (I combined rain and ocean waves, with some white noise lower in the mix, as I have mainly a high ringing around 12kHz ish, and it does the trick for me). If you want a quick solution, the website
Simply Noise does some great 60-min background noises, including the ones I used.
Important: If you are also suffering from hyperacusis (increased sensitivity to sounds) it may not be best to follow advice on the internet and get checked out ASAP until you get the help you need, as from what I can gather the treatment methods are different for people who also suffer hyperacusis with their tinnitus. Try to remember that damage is partly about length of exposure, so while you may be tempted to put in the earplugs when someone is hitting the drums a few times to tune them before any mics/PA are involved in a soundcheck, this is unnecessary in rooms large enough for 100+ people and may encourage a mental fear of loud noises that aren't actually too bad for short durations. Also, get some decent ear plugs instead of the cheapo ones given away for free - not only do they have a flatter freq. response but the cheaper ones don't always offer enough protection for the duration of a gig (usually a few hours). The cheapest I'd recommend are the ER-20 filtered ones available by many different brands for £10-15 (like these ones).
Sorry for the huge wall-of-text, but I know that tinnitus is a horrible thing to deal with when it's getting you down, and hopefully I can help others that love music and life as much as myself and need a helping hand.
