Great article by Stephen Frazier. At one point, IIRC, he was high up in Loop New Mexico.
Auracast Is Actually Here and It’s Not Just About Hearing Loss — Hearing Health Foundation
Frazier forecasts an 8- to 10-year span for Auracast to take over. He seems to predict earbuds, not HAs, will be the driver, and he cites the example of earbud wearers in a stadium being able to hear the play-by-play announcer clearly over the roar of the crowd as an example of the utility that will drive Auracast adoption. He reviews the performance of the VOCE Auracast transmitter (the HERE NOW part).
