Anyone using RTE for low frequency (hybrid)?

Just received my Cochlear Nexus implant a couple weeks ago on the right side. Wonderful surgeon said he inserted a slim full length electrode, but plan was to only stimulate the higher frequencies (for now).
We didn’t talk about using a receiver in the ear, but it’s in my kit of parts I received.
With my prior right hearing aid, I only heard the lows well with a custom mold and small to occluded vent.

I have a hearing aid on the left with 85% WR, but my lows (stethoscope frequency sounds) are entirely absent.

Anyone using this kind of (hybrid) setup, any brand? Curious on your results and any tips.

Congratulations on getting your . Have you been activated as yet?

My in comparison to yours. I have very little residual left now. I did use a hybrid EAS with my N7 for 15 months, it bought in my highs only. I still have good lows though. At around 15 months PO I had another small SSHL in my R) ear, this rendered the hybrid useless, as I didn’t have enough residual left to benefit from the hybrid. Looking at your audiogram you have excellent residual. I’ve not heard about a hybrid for lows though. It would be worth trying just to see if it does. When using the hybrid I used I didn’t have all the features of the NS app functioning.

Good luck to you on your new hearing journey

Thank you.

Activation is 1/19.

I need to update my . For right ear, after my lows I basically have a cliff that goes all the way down to the floor. At least for now, my lows enable an amplified stethoscope and some music that the left can no longer hear.

I have brand and a steep hearing loss - I had hoped to use their “acoustic ear hook” for my lower frequencies, but I didn’t have any useful residual after surgery. I thought it would bother me more than it did - it’s actually simpler to go straight and on the other side. Hope all goes smoothly at activation for you - let us know how it turns out for you!

Edited

Thank you, I will.

I updated my , sorry about that.

My only pet peeve about residual natural low frequency hearing is I still work where I need to be able to use a stethoscope. My implanted Cochlear Nexus right side had great stethoscope clarity with ultra-low frequencies using an amplified stethoscope despite its 20% WR. So, obviously that was a prominent pre surgery discussion and the surgeon expressed a great deal of optimism.

My left side 85% WR has zero ultra-low frequency hearing despite how my audiogram appears. These very low frequencies for heart and lung sounds are not well captured with standard audiograms.

Guess I’ll see what happens! I can use my stethoscope now, two weeks post surgery, but the volume slider had to go from 4/10 to 8/10. Since my bone conduction grossly seems at baseline, I am hoping once I fully heal that my air conduction and cochlea allow for decent residual hearing. Of course, I could eventually lose it. Taking it day to day.

I did connect with a bilateral cochlear implant user on a different platform that is almost done with Emergency Medicine residency and he states he functions just fine with heart, lung, etc sounds. So I am not despairing, yet.

Which hearing aid do you have? Which stethoscope do you use? EKO CORE 500? My Paradise 90-RT could amplify streamed sound even as low as 40 Hz, didn’t check it with my new Sphere.

Phonak paradise 90

Thinklabs one stethoscope. I have been using over ear headphones with a wire to the stethoscope since it is faster than switching my aids from ambient to Bluetooth and back. It’s not because the right hearing didn’t work with my stethoscope.

My left side does not hear the stethoscope frequencies at all, aids or not.

Do you have plans to get a Resound aid for your non side?

You might find if you do, once paired and linked all 3 devices ( phone CI) together and streaming properly, you might hear a lot better with the stethoscope. With the Phonak and CI they are working individually not together in streaming mode and they never will

When/if you get a resound aid it must be “linked” on your ’s mapping computer. The only drawback is you need your phone on you, or near you all the time. The streaming distance is only about 15-20 meters.

Good luck.

1x2.5mm.

When it’s occluded with cerumen, I can hear that the lows are trying to come through, but it’s mush.
When I occlude the right vent, I get a lot of low frequencies.
When I use my amplified stethoscope with over ear Bose headphones, I can detect lows on the left but it’s unusable.
I do have some molds that are smaller an fit entirely in the canal, pin hole vents. I haven’t bothered to try them lately.

Thank you for thinking about the issue!

Thank you.
They haven’t ordered my Resound yet. Activation is 1/19 and they did not seem interested in that.
I may get some on ebay. The quoted price is significantly better.
My phonaks are from ebay 5 years ago, saved $2,000. I just pay for my visits to the audi since it is not bundled with the aids.

What it’s mean? 1 mm diameter or 2.5 mm?

For low frequences and your hearing loss (especially in the left side), the pressure vent (0.5-0.8mm) or even no vent is probably a must especially for your low frequency requirements. For your right eae probably too. I have 0.9mm in my only hearing naturally ear, but I probably could have no vent without any problem.

I don’t think buying Resound is much beneficial especially when you don’t perform auscultation through streaming.

My thoughs about buying new hearing aid despite Cochlear company sound processor:

First Timer - Going with Phonak Sphere
Thank you. I am considering buying LACE AI Pro from Dr. Cliff’s discount link because of its reportedly scientifically proven additional +6 dB SNR after training, which is massive, but it is quite expensive. Regarding Resound, I did my research long ago and again after the Resound Vivia announcement, but I have found no benefit from their binaural offering (EDIT: this is in my case, YMMV. END OF EDIT). Their solution is only binaural streaming, which is not useful in my case, as I want to isol…

So, in short, I have gone with Phonak Infinio Sphere 90 with finally UP receiver with no regrets, although I prefer to auscultate with my cShell temporarily slipped out (I have good LF hearing).

The vent is oval 1x2mm

My phonaks are fine, but my Cochlear Nexus implant only works with the Resound brand for the app and streaming to both devices at the same time. Otherwise I wouldn’t bother.

@dghundt said:

That’s huge regarding your low frequency loss. You can try P receiver with power domes deeply placed (so maybe in M size). Unitron power domes are stiffer than Phonak one.

However, putting new acoustic coupling requires new fitting, ideally -based.

YMMV, but in my case I didn’t find it useful for me, especially when I isolate my ear from the better due to rehabilitation.

I am looking forward to your comments about the Nexa. I believe it will be a very nice system.

As far as streaming goes getting the compatible hearing aid for your processor is a good idea. They work together very well.

is giving you some great advice concerning low frequency sounds and the stethoscope. Once you get all your devices set up right I got a feeling you will be happy.

I appreciate everyone!

If I put my headphones on with the stethoscope attached, regardless of putting the volume to 10, I can’t distinguish the heart and lung sounds. I can detect the noise, but that’s it. I like it to word recognition scores.

Do you feel that I can capture low frequencies with clarity on the left with an aid nonetheless? Open to any trials to see.

@dghundt said:

Left 20%

Right 85%

This appears to be backwards.

If you have 85% understanding in your aided ear I would think you could understand your stethoscope. If you can’t my thoughts are similar to . Your streaming programs can be tuned just like the rest of your programs. Next time you are at your fitters maybe bring this up and test with him. Take your stethoscope with you.

It does seem odd - speech on the left, stethoscope on the right.

Since my right mid to highs are gone, I assumed my very lows on the left were dead as well.

I’ll bring it up and give it another go with my audiologist.
