Some reviews are based on “objective measurements” …the problem is, the ‘object’ being measured is, in real life, a moving target. WHICH of our hearing profiles is being measured? Mine is different than yours, etc.
in other words, what counts as being “an objective measurement”? Maybe a machine that records sounds on a template. but none of us hear that way. Our 'objective" isn’t so much to aspire after what a computer tells us is ‘proper hearing’. Our objective as hearing aid wearers is to find the most functional and rich sound experience while wearing our aid.
those on the Self Programing forum know this. there is no algorythm that will resolve my or your hearing issues, which anyway are changing from day to day.
other reviews are based on adjectives. these last come closer to describing the lived experience of wearing any given aid. But that experience is constrained by the parameters of the individual user’s hearing loss, sound preferences, etc. in other words, adjectives tell us something about how one individual experiences a hearing aid.
The “objective” camp wants information that will apply to everyone, just as math does to physics.
the “adjectival” camp tends to be more modest, and only reports as best they can how a given set of aids sounds to them.
In short…(too late!!!) there is no review of any set of aids that will predict how any individual will love or hate them.
