Resound Preza from Costco

#67

If you go to the ReSound site for the Preza and look at the Smart 3D app brochure available under the Downloads tab, it shows a screenshot, presumably for a Preza, with a music program included on the program bar in the smartphone app, same as for the Quattro’s. http://future-resound.com/

Whatever HA you get, it’s a good idea to read/skim the user guide ahead of time and advise your provider what programs you want set up in the HA’s. The programs added to the HA may vary depending upon how the provider has their default fitting scheme adjusted in the fitting software. I recall at least one previous Quattro user whose provider had just installed the All-Around program and not much more to get the user started. It is hard to find in the Costco ReSound Preza literature any specific mention of the music program but an easy way to solve this is just to call your local Costco’s hearing aid center and ask - or visit that store area the next time you’re shopping at Costco (the HA center’s hours are more limited than the overall Costco store hours).

Thanks, Jim. Believe it or not I had skimmed though most of the material on that link but missed that image…duh! But that’s encouraging. On the US Costco website, there are a bunch of self-help videos on the Preza and the one on changing programs does NOT have the Music one. For sure, I have a Costco appointment in September, so I’ll grill them on that. Maybe it’s a paid-for upgrade. It would be helpful if HA companies listed every feature explicitly and in detail, like when you buy any complex technology such as a mirrorless camera, but they are vague in a lot of areas - intentionally I think. Sometimes makes comparisons difficult.

For the Quattro, the Music program is just a free option in the fitting software program and I naively presume that it’s the same for the Preza. No HA OEM would get very far charging for a music program. Since the Music program sounds different and usually does not aid speech recognition, I can see why a provider might want to leave it off initially especially for an older person just starting out with HA’s during a trial period where if they accidentally got switched into the Music program, the user might wonder why speech sounds different, not as good as it used to be, etc. Button presses of the wrong length can change programs instead of volume, etc.

That makes sense. I’ll update this thread once I find out for sure, should anyone have a similar question. Cheers.

If I knew how to upload screenshots from my iPhone to here I would do so from the app. But this is what I get …

A couple more playing with it

So you can see what you can do with the app

Perhaps if you’re writing a post on your phone you don’t get a dual screen view. On a 27-inch monitor using a browser on a Windows 10 computer, I get the raw markdown/forum code of the post in a dialog on the lower left of the screen and on the lower right, I get a preview of what the finished post might look like.

That was on my iPhone X. I have a 27" iMac at home, but the app is on my phone and I’m still at work for another 40 minutes. Although I can come here on my Windows 7 workstation when not busy, I can’t do much like uploading pictures to it. We stay with Windows 7 as it is most compatible with the various VPN clients we use to connect to our County client networks.

Yup! There are those little ol’ quavers. That’s great news and I appreciate you taking the time and effort to do that. I’m excited to get these for the start of next term. I teach and it’s getting difficult to hear student’s questions sometimes.

I am not familiar with the Quattro and ReSound practices, but I have the feeling that these higher end hearing aids all do pretty much the same thing. I am most familiar with the KS8 (Rexton Emerald 80, or Signia 7Nx) from Costco, as I have them as well as the Connexx programming software, so I can see what they do and what options they have. I don’t have the hardware to actually program them though.

From what I see in the software is that the hearing aid gain from program to program, including the three music programs on the KS8’s remains the same. The gain vs frequency strategy comes from the prescription formula. Some are more intended for speech than others. The music programs typically only play with the other features such as noise reduction, Peak limiting, and feedback suppression speed. That said there is nothing preventing the fitter from adjusting the gain vs frequency correction for the music specific program. It is kind of a trial and error process though.

Separate from that is the streaming program. The normal programs are essentially for sound picked up by the hearing aid microphones, and what you get in your ear is a combination of the natural sound and the amplified sound. The balance between the two is determined by how open or closed your fitting is. However, when you go pure streaming, there is no natural sound. That most often leaves the ear canal short of bass which comes in through the fitting. So it is normal to have a streaming equalizer that can adjust the sound in up to 20 bands to correct for the loss of normal ambient sound. This equalization is applied on top of the equalization used in the normal programs.

The other thing you might find of interest is the anti reverb program. It is intended to null out echos that make it hard to understand speech in auditoriums with hard sound reflection surfaces.

Hope that helps more than it confuses…

I don’t have a clue about a thing that you said. All gobbledegook to me. I prefer to let the fitter who knows what he’s doing do a good job for me. My Costco fitter used to repairs aids, now is an HIS. I’m too old to worry about learning new stuff that doesn’t interest me when I have to keep up as it is with election laws and how the program I support is constantly changing to accommodate the legal mumble jumbo. As for the Preza aids, I am really impressed and happy with them. I can hear much better than ever before. It seems counterproductive, but you turn the volume down on the noise control to allow you to hear closer voices. Go figure!

I have ordered Preza and will get them in two weeks. If I get some useful information, I will share on this thread.

Thank you for all those insights, and very clearly stated. Of particular interest was the observation that the prescription correction essentially remains intact, which makes sense. Then above that is an overlay of adjustments which emphasize certain frequency ranges. I’m no hearing aid expert, but do some audio mixing that includes human speech. The “presence” frequencies are a around the 5kHz region and when lifted emphasize articulation of hard consonants, which improves clarity and the perceived comprehension. Another region is around 2-3 kHz which sharpens/hardens up vowel sounds. I imagine it is these types of frequencies that are lifted in HAs to improve speech clarity (over and above the deficit correction). So I infer from what you are saying, the music mode normalizes these speech frequencies (without changing prescription correction), otherwise many musical instruments would sound harsh or unbalanced.

The strategy to deal with music may vary from manufacturer to manufacturer. I can only speak with certainty about the KS8/Signia/Rexton aids as I have the software.

To be clear they do not mess with the equalization or gain vs frequency for the music programs that are intended for listening to live or recorded music. The equalization only gets applied to correct for the vent loss when listening to streamed music.

The frequency vs gain correction along with the degree of compression gets set by the overall fitting formula or prescription. There are various open formulas used like NAL-NL1, NAL-NL2, DSL v5, and 1/3 gain. Each manufacturer also has a proprietory one that they of course claim is best! These are different approaches that are mainly intended to make gain corrections to improve the speech range (200 Hz to 6 kHz). Some of these formulas may be better than others for music appreciation. DSL v5 may be one of the better ones for music especially if you have decent higher frequency hearing. It kind of depends on your loss.

If one of your priorities is music, you may want to do some research on which prescription method may be best for you, or discuss it with your fitter. These formulas a starting point. The next step is to do real ear measurement (REM) to measure and adjust to these targets. Costco always does this. Next the gains can be adjusted manually based on what you hear.

Hope that helps some.

I think I’m more than up to speed with this now-thanks again. I have mostly mild hf loss. I will mention my requirement when I get the REM done next month.

You might find this article of interest. It is a generic guide to hearing aid fitters in how to get the best out of hearing aids used for listening to music. It does not focus on buying some magic set of hearing aids that is a cure all, but rather takes the fundamental approach of optimizing all the tools in the toolbox that most hearing aids have. I noted that they do not recommend using a different prescription formula for music compared to what is used in other programs.
