I've had tinnitus for 20 years do whatever you can not to catch it. Protect your hearing as best you can. If you go to concerts where earplugs. If you're around loud noises wear earplugs. if you're exposed to a jackhammer wear earplugs etc., etc., etc.
My tip buy and use lots and lots of earplugs. Try not to get ear infections. Learn if foods are causing adverse side effects to your ears through food intolerances. Do not use q-tips in your ears.
If you use earbuds for your tunes do not play the music very loud.
