Hi MaryAnn Smith, and Welcome to the ANA Forums!
Thank you for making your first post!
My experience is a little different that alabamajane's (although the Cochlear BAHA is a great option to consider).
As a result of my acoustic neuroma, I have 12% hearing also in my left ear. When I go to a drive-thru, my good ear is inside the car. I can hear that the person taking my order is saying something, but I cannot understand it.
So, my audiologist recommended a CROS hearing aid system. With it, when someone speaks in my left ear, there are microphones in the hearing device in my left ear which serves as a transmitter. The device transmits the sound to a receiver in my right ear (my good ear), and I hear whatever someone said on my left side.
So now, when I go through the drive-thru, whatever the person taking my order says, I can hear it clearly, but in my right ear. It takes a little getting used to, and the CROS systems are not cheap, but I don't think I could function in my work without it. Any audiologist should be able to tell you about the specific CROS system they sell.
Best wishes in your quest to hear better!
