    Default Hearing aid experts? PHONAK AUDEO V70-312 , COMPILOT II

    Ok I inherited a bunch of electronics and it includes a single Phonak AUDEO V70 312 hearing aid and the COMPILOT II which is a phone and TV Bluetooth device that has a neck loop.

    First

    I looked up the FCC filing for the V70 and was surprised to see a 10.6 MHz Part 15 (FCC low power) emission from the hearing aid. Why would the hearing aid transmit? I can see why the COMPILOT would be transmitting to the hearing aid via the loop but not the other way around.

    I though the communication would be via magnetic loop but it appears a 10.6 MHZ carrier is used?

    Thoughts, how does all this work?

    Secondly. The hearing aid has a red dot for right side, yet the in ear receiver wire is for left side. Can this simply be bent to facilitate wearing on the right? Is there any difference in a right versus left hearing aid a large from the red or blue dot and the programming?

    Finally , how are these programmed? Is it via software and modem tones? Any DIY software to do this? I saw a service that does this remotely so I suspect that modem tones from a PC speaker is how this is done.

    Again, tell me what you know.

    I would suggest that the low power Tx is to provide some "fill" for the other ear. Remember, those w/o hearing aids do hear with BOTH ears, and the loudness gives some idea of proximity and direction. If you have a hearing aid in each ear, if they fit correctly, they can act as ear plugs which does nothing to assist in hearing until they are turned on.
    I'm out of my mind, but feel free to leave a message...

    The User Manual might be a useful source of information.

    .

    If not, contact the manufacturer, Phonak.

    1- Hearing aids actually talk to each other, at least some higher end models.
    2. Left and right are differently programmed, nobody has the same two ears but the dots also help the user because right won't physically fit on the left either.
    3. They are usually programmed with an adaptor that fits inside the battery compartment, I haven't seen any standard or DIY options there. I only have a little experience with Siemens, though.
    Update: A deletion of features that work well and ain't broke but are deemed outdated in order to add things that are up to date and broken.
    Compatibility: A word soon to be deleted from our dictionaries as it is outdated.

    I wish I had known these had small transmitters. My Mom would lose one or the other on occasion and in the end, had only one. At $3,800 for the system, losing one was expensive. Yes she had insurance, but if you lose same ear twice they don't cover it, go figure. I could have swept her place for bugs and found the other one.

    So now as her executor, I am trying to decide if they are hackable or saleable.

    Any ideas for a hack?

    Well as her executer you now have a very good chance to find the other one.
    As it is a behind the ear type it is very sellable but useless unless you have both. The left<>right talking feature is what makes this work properly.
    You can play around with the app, a bit of EQ, etc:


    but I have never heard of any hacks.
    They need to be programmed by a specialist who analyses the users ears, this is not something you can do by yourself.
    This is more complex than just equaliser/bandpass settings, there need to be frequency dependent thresholds determined for the dynamic compression which set incorrectly could damage hearing prematurely.
