Cochlear Osia vs Cochlear BAHA for SSD

I know. Osia is the newest bone conducting system I am aware of that.

although I’ve seen that a lot of folks don’t include the Osia when they speak about Baha aids.

Yes, because it was released relatively recently, maybe about 2020? In my case I wrote “CI/Baha” as a brachylogy.

it uses the mastoid bone to conduct sound to the cochlear nerve.

The sound in the form of a mechanical wave is conducted to the cochlea and then, inside the Corti organ, is transformed into an electrical impulse that stimulates the cochlear nerve.

The CI is a device that bypasses the cochlea and Corti organ and directly stimulates the cochlear nerve.

So Baha/Osia still requires at least one healthy cochlea.

The ENT classified my Los on my left ear as sensorineural. Regular hearing aids didn’t work on that ear, it only made the unintelligible noise louder. But, the Osia seems to be sending intelligible sound to the faulty ear. Maybe my brain is playing a trick on me and makes me think I’m hearing the sound through the left ear, when it’s really coming through the right ear.

Or is something happening in my brain? Does the brain hear the intelligible sound in the right ear, and the unintelligible sound in the left ear and somehow know what intelligible sound house with the corresponding unintelligible sound. Almost as if my brain has become an enigma machine and is decoding the unintelligible sounds?

TexOkie, your questions are beyond my pay grade. However your statement above seems possible. I only have an Osia on my right ear, but the device also has a carry over effect on my left ear. It’s difficult for me to tell where sound is coming from when I wear this device. In any case, it sounds like your Osia is performing pretty well!! As long as it works…fine!

Another question for you. I’ve been using the Kirkland 675 Zinc Air Hearing Aid batteries in my sound processor. They last about three days and are about 50¢ each if you buy them on the big card.

I was having trouble with using my iPhone 13 to stream audio for phone calls to my Osia. I could hear them, but they could not hear me. Replacing the day old battery with a new battery resolved the problem.

I asked Cochlear Support about this and the first thing they asked me was what kind of battery I was using. When I told him, he told me that to stream phone calls takes a lot of power and the Power One batteries could deliver the necessary power over the life of the battery and the other brands were made for standard hearing aids and would work for normal hearing aid functions, but not for streaming functions.

What batteries are you using and how they working?
