Over the last two weeks, I have been using a single right-side Signia Silk 7 with a boost matching the hearing loss shown on my audiogram, along with a tinnitus notch from 7.5 to 8.5 kHz. I can't say yet whether my level 5 tinnitus has decreased, but mentally there is definitely an improvement. My brain feels more balanced, and I am enjoying life more again. It may take another month to see whether the tinnitus level has actually dropped.
There is also an option to add a masking noise generator program, but for now, my provider chose to start with the notch only.
