I was thinking about that the other day. Faire Jour says im missing the high frequencies and most of the mids. That is true but what if transposition could "pull" those down to the lows? Many of us severely-profoundly deaf people have enough residual low frequency hearing to benefit. Many of us have 110db+ loss above 1000Hz including cochlear dead regions in the highs and even the mids.
With transposition algorithms, HA wearers can access the highs by having them shifted downwards. Can't hear the birds sing? Have the 3000Hz shifted down to 1500Hz, 1000Hz, 500Hz, whatever works best for your hearing. Most of us have little or no idea what high frequencies sound like so it won't sound strange to us. We will notice that we can hear more environmental sounds but those sounds will be familiar, they just will emit from unfamiliar sources.
Speech should improve. The high frequency S, F, TH, CH, SH, K sounds likewise can be shifted down till it's easily heard. Plurals will be able to be heard. In fact I can somewhat hear plurals as the S sound is not a puretone but has some lower frequency overtones. With transposition, ill hear the S much better and louder.
Transposition won't help the profoundly deaf who have 90db+ loss at any frequency, even the lows. There has to be enough residual hearing at 500Hz and below. It will help greatly if you have some residual hearing in the 750Hz to 2000Hz range which compose of the mid frequencies.
I will be having transposition programmed on my HAs along with more gains and other programs. I am prepared to give my brain time to get used to transposition and make it work for me. I will need sounds to be transposed down to a range between 500Hz and 1000Hz. I will also have a different program without transposition(my HAs can store up to 4 programs selectable with the push of a button)
I look forward to hearing all the keys on the grand piano in my parent's house. Currently, I can't hear the last dozen or so keys. Using vitrual piano on my computer, I can't hear the last two octives. I also look forward to hearing birds, crickets and even knowing when a hinge is squeeky so it can be oiled. We will no longer be missing out on sounds, they simply will sound different to us than to hearing people.
