@bobvann, glad you finally heard back from your audiologist.
I've been using this technology for several months now & know exactly how it works. My left ear has a definite greater hearing loss than my right ear. I unfortunately experienced SSHL in my left ear, but through a series of steroid shots, regained 60%. I am certainly not deaf in that ear. After careful and complex examinations by my highly qualified audiologist team in New York, along with my Board Certified ENT, I qualified for and am benefiting from using the bi-cross system.
I want others to know that one does NOT have to be completely deaf in their "bad" ear for the bi-cross technology to work. I'm proof of this.
