High Frequency Sound Issues

MDB I finally have an appointment for Thursday. I will discuss this. I think sibilance is an issue but the primary issue is the kazoo sounds. Thanks to everyone for there input. It had really been a help to me.

Brian987 I certainly hope I am not relegated to the kazoo sound. I honestly would rather not have them as have the kazoo in my ear but that is not a good option either. I have not trialed any other brands with Costco. Audi is sure these are best for me, mostly because of my small ear canal, but I will bring up the subject at my appointment on Thursday. I tried some Oticon before I tried Costco and the sound was very good but I had a terrible time with them in noise and I realized I was in noisy situations more than I realized.

Bringing my story up to date…
Over time, my audi made multiple right ear impressions including one with mouth held open & we tried a handful of molds. There was trade-off between sound quality & discomfort with the different molds. An extended skeleton w/lock holds in place better & offers nearly the best sound quality, with only short periods of discomfort. I’ve been using it for a month or so.
I can only conclude that my right side TMJ issue is at the root of my fitting challenges and I’ll never get as much help from HAs as some. My current hearing experience is…
-Sound from audio speakers is mediocre—or worse when the HAs pick up speaker defects you weren’t hearing previously. [I had to laugh when I read a comment suggesting you need to increase your electronics budget after getting HAs.] Streaming offers a good solution, tho. A Widex compatible phone model for streaming music, calls , etc. and the Widex TV streamer for TV content supply good quality sound. Bluetooth is about 98% reliable/brief interruption free.
-Environmental sounds are usually much more apparent.
-Quiet conversation is somewhat improved.
-Restaurants that are busy/have challenging acoustics are still quite troublesome.

Thanks to Bimodal—you were on target with most all comments & suggestions—and thanks to other commenters for your input & encouragement,
B

Thanks of bringing up your experiences.

Why only for a month? Discomfort issues?

And which coupling solution your have finally? Canal lock? What diameter of the vents?

How did your mold work out that you were waiting for so long back in the spring?

For Sphere - cShell must sent to remake, because I’ve got too large Acoustically Optimized Venting based (AOV) based on audiogram, instead of 0.6 mm diameter vent requested in order form.

For Paradise (~5y old spare hearing aid) - a bit better, which means that there is a 0.9 mm vent instead of a 0.6 mm one, and the cShell has a smooth surface instead of a rough one, which makes it slightly more prone to slipping out.

You’ve sure struggled to get fittings manufactured according to your order For one reason or another, finding/maintaining a proper fitting can be a never ending process I guess.

I’m getting by pretty well with the soft skeleton mold for my right ear—it usually holds position and is comfortable most of the time.

I read somewhere recently that an up sloped canal (as my right ear has) is likely to conflict with the TMJ (even a normal TMJ), and so a custom mold is necessary based solely on my canal’s anatomy. My audi/I took > 6 months to get there, but better late than never

That “kazoo” effect sounds like something worth testing by frequency rather than just turning the overall treble down. You could try checking individual tones with https://frequencylama.com/7 and note which range is most noticeable, then bring that info to your audiologist. Might make the next adjustment a little easier.

libiahong, Thanks for posting that frequency generator link.
