Due to an acoustic neuroma in my left ear I have diplacusis, where I hear everything about a half-step flat in that ear. As a musician, this condition causes me huge problems. However, I believe that it also affects my speech comprehension.
I trialed a pair of Widex bi-CROS hearing aids. Objectively, I thought they improved my speech comprehension a bit, and they certainly improved my ability to hear music correctly and to sing in tune. However, my audiologist recommended against using bi-CROS because I still have some usable, aidable hearing in my left ear. He is concerned (as am I) that if I stop aiding my left ear that my ear will lose its remaining hearing ability due to lack of stimulation.
So I am thinking that a possible solution might be to use an RIC bi-CROS system IN ADDITION to aiding my left ear with a normal RIC hearing aid. My idea is to use double-sided tape or some other adhesive to place the microphone-only side of the bi-CROS HA and the regular HA together side by side on my left side. Only the wire from the regular hearing aid would go into my left ear. On my right side I would wear the receiver/hearing aid of the bi-CROS system.
Then when I felt the need for clearer speech or accurate music comprehension I could reduce or mute the volume on the actual HA in my bad ear and turn up the volume on the bi-CROS mic on the bad side. The idea is that I would be aiding my bad ear almost all the time and I would only be using the bi-CROS system by itself when I really needed to.
Obvious downsides are added physical bulk behind my bad ear, increased complexity in trying to manage two HA systems on the fly, loss of the benefit I have now of having two fully-functioning HA’s that “talk to each other”, and added cost.
I’d like to hear any ideas or comments anyone might have, especially from the pros on the forum. Has anyone tried this? Could it work in practice? Thank you.
