No hearing aid model performs real ear measurement “automatically.” The Genie2 software from Oticon does help to streamline real ear but, as cvkemp mentions, it still requires that probe tube microphones be inserted in your ears while your hearing aids are on. Measurements of the sound are then taken, verified against target and adjustments made within the fitting software.
When a provider mentions, “automatically,” they may be speaking to the prescribed targets which the software provides for the average person with your hearing loss. Real Ear takes this a step further by customizing the delivery of sound so targets are matched perfectly based on the unique anatomy of each of your ears. You will get much better results by insisting on real ear measurement.
