I'm wondering about baha's and cros' too. I have heard that bahas are for conductive loss, but maybe I'm wrong. I don't have much left in the bad ear, but its sensioneural loss. The HA just seems to amplify the noise, so I've stopped using it in that ear. Works far better in my good ear. With a baha, there's a bolt in my head (where, exactly) which transmits sound to the good ear, right? Does the good ear get some kind of receiver?
How is it different from Cros? Also, if I have something degenerative, like meneires, then my good ear will probably succumb as well. What then? I've been trying to chase my hearing with an aid, but feel like it was a waste of money. If these aids rely on a good ear, and I lose that one too, will they still work?
If I sound a bit irritable, forgive me. I'm surprised by how strongly I feel about losing my hearing. I remember as a kid, I read about Helen Keller and mused about which sense would be hardest/easiest to lose. I remember thinking it wouldn't be so bad to lose my hearing. Ha!
