Tinnitus is not well understood which is why there are so many causes and treatments suggested by qualified people. What causes and treats it for one may not be similar for others. It is commonly associated with hearing loss but not always. Treatments usually are "retraining" or "masking." Retraining involves mixing and learning to habituate. This involves mixing a sound source that is audible but not masking the ringing totally. Maskers wipe it out. One thing research clearly indicates is counseling is key. Anxiety is enhanced as the ringing is viewed as a negative thing and this grows and grows. Sorry for the long post but I hope this helps.
