Re: Affordable hearing aids extant?
I may be a bit out of the loop. I'm not clear on what data suggest that
untreated mild to moderate hearing loss (not severe to profound) leads to
the decline in cognitive function or irreversible neurophysiologic damage
suggested by Magilen.
My understanding was that deficits due to auditory deprivation could be
overcome to a large degree if amplification was initiated (hence not
irreversible). Regardless, if the losses we are talking about are mild to
moderate these individuals are receiving auditory stimulation (although not
all of speech is audible) during conversational speech, particularly in

I picked up from Magilen's argument that the use of poorly fit, one-
size-fits-all approach would likely lead to frustration,
dissatisfaction and increased hearing aids in the drawer. It could be
off-putting leading many to believe that devices are useless. Not to
mention irreversible neurophysiological damage incurred for lack of
stimulation due to poor fitting.
