I saw this news report, as well. It bears keeping in mind that any retraining of the brain involving an exterior hearing device is dependent upon having some hearing in that ear. In other words, for single side totally deaf patients, it will not be useful for tinnitus on the deaf side. That being said, if one's tinnitus is bilateral, then sound therapy can have a better chance of working.
