Hope you can get some relief. So he said "probably" and "might"...wouldn't it be great to get more like a "here's the issue and here's a solution" ...curious whether you talked about the out-of-phase noise cancellation techniques.Altitudinous finally went to ENT appointment yesterday. I have moderate hi frequency hearing loss that probably is what causing the hi pitched noise I hear (Tinnitus). Probably caused from my Air Force aircraft mechanic career field. He said hearing aids would help the noise during the day and a noise machine might work at nite time when I go to bed to mask the noise.
