If you can take time to go back over the comments in this discussion, you'll find several comments on this type of tinnitus sound. I have sensorineural hearing loss in both ears and use a hearing aid and a cochear implant. Often I feel as if there's a motor of some kind on in the basement. It's easy to ignore, but it's there. Tinnitus affects people in many different ways, this being one of them.

Are you able to ignore it?
