Would like quantitative Information of effectiveness of this technique !!
Fiddling a bit with hearing aide technology, I first was looking at human Frequency response which we discussed the other day being from 20hz to 20,000 hz and that, as we age, we lose at both ends but mostly at the high ends.
A quick test of mine was done using web.engr.uky.edu/~donohue/audio/fsear.html which runs from 40hz to 18,000hz and a quick test showed me limited to 100hz to 8,000hz.
And, from other papers, I learned that some hearing aides have “Frequency Compression” capability that takes those high frewuency sound that we can no longer hear and compresses them down into a range that we can hear.
Seemingly VERY NEW, an paper at What Is Frequency Compression in Hearing Aids? discusses it and then mentions some hearing aides that have that capability.
SEE BELOW and those very new “Phonak Audeo Paradise” (four different quality levels which I may have already sent you) have that compression.
Seems to me, if done right, they could bring those high female voices brought down into one’s hearing range and help over-weight those background noise levels that limit one’s hearing .
But, for certain, to work right the Audiologist would have to have the equipment and the knowledge to provide the proper level of compression so that one must find someone who has had training and can discuss any or all of the devices below and, after one is chosen, adjust them properly to one’s hearing capability.
NOTE: I suspect that many audiologists may not even know of the technology – even when they’re seeling the models below – nor will they have the equipment to properly set them up for each indvidual.
