Nice to hear that a company that is not a hearing aid manufacturer is attempting to make their product(s) work with hearing aids.
That statement implies that the LE Audio “standard” doesn’t require negotiation to determine capabilities of the nominally compliant devices. Most hearing aids don’t need a frequency response beyond 10 kHz as the speaker (receiver) has little or no output above 10 kHz. That implies that a sampling rate of 24 kHz would be more than sufficient. The requirement to disable a “feature” that many would find desirable (high quality music) seems odd, at least to me. Or doesn’t the “standard” require transparent interoperability between devices from different manufacturers?
A while ago I tried to look up the capabilities of the new codec for LE Audio. I noted that some parameters that would be associated with high quality audio (high sampling rate and large bit depth for example) seemed to have the effect of requiring increased latency, at odds to one of the selling points of “low latency” which is useful for many hearing aid users.
