Be sure and let us know how your visit to audiologist goes. I think I would listen to advise and then go home and research before sagreeing to purchase anything.
Have you visited the American Tinnitus Assoc. Site, ata.org, to read the description of tinnitus and hear various sounds? Very informative. As has been stated, tinnitus is not "in the ear" hearing function,, it is a brain perception function,,, as I understand it,, it is the brain trying to make sense of the distorted sound from that side.
If it were a hearing issue which could be "fixed" with hearing aids etc. then those of us who are SSD ( single side deaf) could not possibly have tinnitus on our AN side and many of us do,, myself included... White noise machine by bedside does help sleep.
Good luck to you and please post to let us know what you find out. I would just hate to see you spend too much money on something to "fix" it unless it's " money back" guaranteed...
