Hello, I am new to this forum. I have had mild to moderate tinnitus for about 20 years, with a constant whooshing sound and ringing and steely sounds coming in and out at the 1330, 2600, and 6700 hz range. It became worse with hearing loss caused by several operations for cholesteatoma. The T has become louder this year. Not sure what has caused it Am looking into notch therapy and wonder if any of you would know if notch therapy is effective with moderate to severe hearing loss. My audiogram shows db loss of 60 db up to 90 db in the higher ranges. Would appreciate any information you may have.
