Lack of frequency coverage by Signia C&G 7IX vs. countermeasures

I have a question: Does the presented frequency gain coverage graph (gray area) for the Signia Silk C&G 7IX hearing aid represent the following:

  • this hearing aid is too weak to amplify 8 kHz and this range is completely lost, or
  • because it is too weak, it redirects 8 kHz hearing to a lower frequency (e.g., 6 kHz)?

Yeah it’s outside its range just, nothing missing for you tho, as in no speech at that frequency, it won’t shift it unless you have (compression)set in Connexx.

@tenkan , there are voiceless sounds like “s”, “c” and in my language also “ś”, “ć”, etc. :-), which reach 8 kHz. Thank you for pointing out the compression (redirecting to lower frequency) option, which my priovider certainly used in this situation.

Redirecting to a lower frequency is only done through a programming feature and is (typically) not activated until the programmer activates it. The shaded area is kind of an estimate in a way i.e. it is the manufacturer stating that they are confident that thresholds in this area can be adequately addressed with the receiver in question.

Maybe, maybe not. I don’t know how to explain this but my story.

I have dead zone around 2khz onwards. I do hearing test by . And I do in-situ audiometry. I can pretty sure my 2khz onwards is no go. I have Oticon Real with Frequency Shifting enabled. With 4k-6khz will be pulled down into 1.5k-2k zone.

One day, out of nowhere. I heard something I never recognize before in my life. It coming from the scanner beeping sound in the office. I was huh? what is this sound range? why I never heard it before?

My sound spectrum analyzer tell me it is 2.7khz range. It dominantly spiky at 2.7khz. My head tell me this is impossible. Hearing aids should not able to help me with 2-4khz zone. Even frequency shifting ON. It not make sense why I can hear 2.7khz.

Even my previous hearing aids, Zerena 9 can’t do this. I test it. No matter programming I done to it. When I use Oticon Real. I can hear it. What… but it is good to hear it again, I guess.

So to answer the quote. Maybe. Maybe it not help you.

But your not actually hearing that frequency, obviously it’s being shifted to a range you can hear in the Reals.

Magic! I don’t know it help me or not help much at all. But it good to be surprised why I can hear it.
