Pretty neat, if true. I have tinnitus, as well as being hearing impaired. Every little bit helps.
I got it two.
And my tinnitus varies leaving me with a varying ‘noise floor’ in my hearing.
At times in a quiet room I can hear good speech on TV perfectly.
At age 68 I find noises making it much harder to discern conversation than in earlier years. Tinnitus just being one source of sounds in that noise floor. Other talking in the general area mask my ability to understand as well.
