Thanks for video and update, about to get these The Silk Charge&Go IX next week. Beautiful Taylor and smooth paying. well done.
Thanks for watching and the kind words @chrisdoe6890! Best of luck with the Silk, I'm currently working on testing those now.

Killer guitar work 🎸🎶
Thank you Abram!
Hi notes were very clear.
I thought so too, especially for a nylon string guitar.
- Steve
Nice test, thank you. Please advice how to setup de EQ inside the Signia software programming! Thanks!
Thanks and glad you enjoyed it. I set Silk IX to the default manufacturer settings without any personalization or real-ear measurements. So what you hear should be pretty close to what most people will experience in the real world. With that said, there are many physical and setting changes that can be made to hearing aids that will generally improve music audio quality.

Great!
Thank you!

Many questions:
I'm new with the Signia Pure C&G T 7IX.
What was the setting on the APP. Manual or auto on Directional hearing?. To hearing the music with your instrument sounds.
Does this device auto adjust loud noise environment. ie music, not head banging music.
Thanks
Hello David, everything was left manual/automatic after programming them to a common mild sloping to moderate hearing loss.
Yes, the volume adjusts based on the environment and sounds present (with both compression and settings).
Thanks for watching and good luck with your Pure C&G.
-Steve
What specific loss audiogram did you program those with? That is a pretty striking difference!
We use an N3 configuration which is a mild-to-moderate sloping hearing loss (Bisgaard, 2010). You can find an image of the specific thresholds around 2:30 in this video.

Hello,
What about the difference with the Widex Sheer 440? They advertise that one as especially good for music, which Signia doesn't do. I have the Signia's for trial, right now with semi open domes because my lower freq. are good enough. But i experience, esp. with voices, also in music(!), a rough, distorted sound. Can you help me with advise?
Hello Reteph,
Both Widex Moment and Signia C&G scored similarly for streamed audio. Here is a link to HearingTracker's comparison page where you can more easily see the stats and hear the audio files for each (www.hearingtracker.com/hearing-aids/compare/widex-moment-sheer-440-vs-signia-pure-ix-charge-go-t-ix-7ix).
Regarding the distortion you hear, a few things come to mind. It is worth noting that hearing aids are generally programmed for speech clarity. These settings tend to differ from those best for music sound quality. Id speak with your audiologist and see if they can provide a dedicated music program with specialized settings (e.g. broader frequency response, reduced compression, increased max power output, disabled frequency lowering/compression).
These adjustments are very specific to your listening situations (streamed music, you playing acoustic guitar, live performances, etc.). For example, It louder situations like live performances it is generally better to remove your hearing aids and use quality musician's hearing protection.
Hope that helps and good luck!
- Steve
@@hearadvisor Thx, esp. for the link!
It seems the Widex is some better!?
How come? The Signia goes to 12 kHz and has 48 channels and 20 bands. So much more than the Signia.
For me direct listening to an excellent soundsystem is the most important, esp. hearing true focus, space and depth in the sound.
So what would be your advise?
The Signia has 'Sound Smoothing' does that influence.the general sound e.g. maybe the somewhat rough sound on voices that i experience?
PS: It is strange the difference in loudness in the last 2 soundsamples of streaming (initial and tuned).
@Reteph58, as I'm sure you know there are many variables that influence music sound quality. Bass response is a major one that may outweigh the impact of extended high-frequencies and extra channels. You can find perceptual studies assessing this across both normal hearing individuals and those with hearing loss.
Again, I would find an audiologist who specializes in music and have them program your devices. I'd wager this would make the biggest improvement in sound quality regardless of the company you go with.
SoundSmoothing is Signia's lingo for transient noise reduction algorithms which attempts to reduce the annoyance of sudden loud and or impact sounds. It is commonly best to have this turned off for music.
Any loudness difference are the result of changes to the frequency spectrum (the volumes are matched at 1 kHz during calibration).

What about Notch therapy? Why does nobody talk about notch therapy? They put notch therapy in these. Does it work or not? What the heck?
Hello @donna8407, thanks for your comment. We are currently focused on assessing the audio performance of hearing devices and have not broached tinnitus. I would recommend searching the literature available on Google Scholar regarding the differences between conventional and notch based tinnitus therapies. My understanding is both offer similar benefits.

Ok, I've been playing for 50 years and using hearing aids for the past 4 years. So far every hearing aid I've tried shifts the high frequency range out of phase with the original source and my guitar sounds like a Sitar. This is the first time I've heard guitar this clearly through hearing aids. I wonder, though, if my experience might be because of positioning, my ears are generally located behind the guitar rather than in front like your example.
Could you possibly do a similar test with a set of Jabra or Resound hearing aids?
Hi Chris, thanks for watching. I know exactly what you are talking about regarding the Sitar sound. It occurs due to the processing delay in hearing aids. Even though it’s milliseconds, it’s enough to cause phase issues when the hearing aid sound mixes with the direct sound entering your ear.
I also found IX to provide a cleaner sound in this regard. A few thoughts come to mind. Newer hearing aids have lower processing delays which may reduce the phase issues. I was also using “sleeve” domes which are slightly more occluding than your traditional open domes. The more plugged your ear, the less mixing between processed and direct sound.
Do you mind sharing what devices you wear and what the ear tips look like? I do plan to create more vids like this so thanks for the recommendation!
- Steve
@@hearadvisor No problem, I had come to the same conclusion regarding processing delay. In fact I was able to reproduce the sound via my recording studio. I used my audiogram as a template for an E.Q. filter, copied the upper frequencies and pasted them back in with a 2ms delay. My audiologist agreed with the processing delay diagnosis. I have tried Resound One and am currently using the Jabra Enhance Pro hearing aids with open domes. I have other domes I can experiment with, but haven't had much time yet. I'll be testing them out as soon as I can! Thanks for the tip!
I am fortunate that I have a good knowledge of audio signal processing, as well as having over 35 years in I.T. behind me. There isn't much I cannot figure out. My hearing requirements aren't something that audiologists come across every day, so finding someone who can work with me has been a bit of a challenge. I now have my own fitting software and NOAH link so I can play with my settings, then when I return to my audiologist, we can tweak them even further.
I got distracted when you mentioned recording studio (I’m an audio engineer as well 😃). Really interesting to hear your experimentation, engineers make excellent audiologists because they know audio, DSP, signal flow well. So definitely glad you have that background to support what you’re doing.

Also note that the guitar you're hearing in the video is only the direct audio feed from the aids (I assume) therefore you're not hearing a delay relative to the direct/live sound from the guitar. I.e. this video only plays one audio stream so there is no original audio and therefore no delay.
The eartips were not completely plugging the ear so this audio is actually the combination of both pathways (natural audio from guitar to eardrum/mic and the processed hearing aid signal to eardrum/mic). I would generally expect a more "phasey" sound due to comb filtering so this was a bit shocking to me.
- Steve
How much bigger are they than the Silk x batter model?
Hi @richdiorio3650, I do not know the exact dimensions. However, they are very close in size and regarded as "nearly-invisible" in ear.
- Steve
Is Widex hear aid water proof and dust proof _for 110db+? Please tell me delears on Jalandhar Punjab India _?
Many Widex hearing aids are IP68 which is currently the highest rating for hearing aids.
- Steve
Does this sound good or bad in comparison to other hearing aids? I find it bad...
Thanks for your comment @miracoli16. These devices were adjusted for speech clarity, not music sound quality. With that said, their sound quality is much improved from older generations which is great to hear.
- Steve
@@hearadvisor
Are there programs in the app to switch to a music program when needed?
My audiologist will not recommend these due to my level of hearing loss. Bummer
Sorry to hear that @georgephx, but there are similar styles available that will work for more severe hearing losses. Best of luck!
