I wanted to try this for auditory processing disorder, but I passed the hearing test with flying colors, so it won't let me try. Is this some regulatory thing?
Not likely. It needs to build a profile of what sounds you can’t hear in order to know what to specifically make louder, if there’s nothing to specifically make louder, then the feature cannot work. Just turn up the volume, or increase the noise cancelling, or turn on voice isolation, or whatever you actually want it to do.
That’s an interesting idea, but I wonder, how would it know who you want to hear? Like if I’m sitting at a long table for a big family meal, I’d want to hear everyone, but if I’m sitting on a bus I’d like to only hear the person I know, sitting next to me. I can’t imagine there’s a good way to differentiate those situations.
