I was chatting with someone on another forum about the automatic adjustment settings that allow the hearing aids to learn over time if you frequently turn the volume up. I am curious as to a bit more on how this works. Does it relate to individual programs or across the board? For example, if I always turn up the volume in program 1, will it increase the volume of only program 1 or all the programs? My program 1 is still ridiculously quiet but I don’t want it to “learn” to turn up the whole hearing aid on every program. Equally if P1 is too quiet and P3 too loud I will just end up with no effect from volume learning unless it’s program-specific. I don’t think it would be well received if I booked a review appointment just to get this adjusted. How many times do you have to increase the volume before it learns?
Is there a limit to how much they can be turned up or down by user preference logging? I was thinking of 2 examples, either of which could be done by my mum! Audiology sets the volume appropriately for a new user, but the user, having not been used to all this influx of new sound, turns the hearing aids down regularly day after day to remove this unfamiliar sensation. Gradually, the hearing aids “learn” that this user needs a lower volume setting, and she ends up removing all the gain and restoring her previous comfortable but not very functional level of hearing.
Equally, imagine a patient who doesn’t take great care of the instruments. Each day the hearing aids don’t seem to be loud enough, patient turns them up. Next day she turns them up more, turns them up more, gradually the volume learning mechanism realises this patient needs her hearing aids much louder. Until her daughter arrives and cleans the wax out of her earmoulds, whereupon patient puts clean hearing aids in and practically blows her cochlears inside out.
Are limitations in place to prevent either/both of those scenarios? At what level is it limited, is it in relation to original settings or just that it will not exceed the maximum output?
