I went to a free online wave generator at audionotch.com. It was pretty good. It helped me determine (to the best of my ability) that my left hear tinnitus was around 8500 Hz, while my right ear was closer to 7800 Hz.
I’m hoping that HA’s will be able to provide my brain with enough of a signal in these areas to trick it into not ‘producing’ those frequencies to fill the void. From what I understand, I have about a 50-50 shot. If regular old HA’s don’t work, I may try a HA with the masking feature that produces these waves at a low level, and perhaps force feeding my brain these particular sound waves will temporarily stop the tinnitus.
Of course, the irony being that I don’t hear ~8K+ sounds worth a darn in the real world. But they are produced in absolute stunning clarity in my brain’s made-up version.
Fingers crossed here!
