No, not Noah. No one needs Noah software for anything! Audi’s use Noah as a database for many clients, and to launch various manufacturer’s fitting software.

At End Fitting when you click SAVE AND EXIT you get the opportunity to enter a Session Comment. That Session Comment is your Session Name (same thing).

Next time you run Genie2 use the (> arrows) on your client to find and select a specific Session.

It’s easy to test. But after testing you may want to cleanup some of the testing Session names in order to avoid confusion. There is a delete function for a selected Session when you are browsing your clients/sessions.

@jferris33 How about some pictures. Whoops, I meant to direct this @TRY

  1. End Fitting
  2. SAVE AND EXIT (then you get a popup)
  3. Check to save in stand-alone database
  4. Type in your Session comment/Session Name
  5. Click OK

Volusiano,

Thanks for pointing out the Speech Rescue settings on my graph. I had read your posts on that topic in another thread and for some reason thought I had mine set to the #1 setting but instead it was set to #10. I have just reset it to #2 and am going to give that a try for a while.

Here is what my Audiological view graphs look like now:

I would also like some help with interpreting this audiological view graph if anyone would like to chime in.

PVC,

Your description of the session naming process is exactly what I do with mine. At the end of each session I just type in a comment that describes the changes I made, then next time I can just select that session from a list of previous sessions that comes up when I select the client.

I think that your pictures cover what you are describing very well but I will be happy to provide some if you still want me to.

When starting a new DIY session from already programmed aids, do you need the session file from your audiologist or can you pull the data directly from the hearing aids? (Including REM, specific frequency gain tweaks, etc.)

#35

gkumar,

As best I can tell the Genie 2 software will pull the existing program from your aids when you first connect them. When you finish your fitting session you can then choose to save any changes to your data base (local, not NOAH) and/or the aids themselves. See PVCs pictures above - it shows check boxes where you can determine what will get saved.

You do need to fill set up a client file and fill out an audiogram with your numbers before you start a session. As I learned earlier, you can input the AC (air conduction) readings from your audiogram into the one in Genie 2. I’m not sure about other numbers from your audiogram - maybe someone else can chime in on that part.

Whoa. THAT ARROW! So, it’s not just a little triangle. I wish I’d know before and I wish my technician had known when he lost all my data at the last FW update and we had to hand enter it from my previous report. Thanks.

In the upper right hand corner of display, click on the Question Mark button, then click on Audiological View, then display it, then Print it. It will be 2 pages. You can use it to work your way through the graphs.

Back to the Audiological view graph, click on the button above the CR button. It displays Output, MCL, and MCR curves. Click on all of them, and they will be added to the graph.

Then use the Signal type button(2nd from top) to show the instrument reaction to different environments. Go through the different signals. You should pick up on it pretty fast.

My very very unprofessional interpretation of your loss is you have normal hearing in your right ear up to 1K.
Almost the same in your left ear. Looks like the aid gives you some amplification at 1K in the left ear. Both ears drop off from 1K to 8K. The gray area in the graph from 1K to 8K above the colored zones is the input signal to the aids. The lighter colored areas of the colored zones are the outputs of the aids. With the MCL and MCR curves displayed, you can toggle through the signal types and see how the aids outputs are merged into the curves.

Luck.

Fred,

Thanks very much for that info on the audiological graph that Genie 2 displays. I think that I am making progress in learning how to use some of the tools in the Genie software.

After Genie has programmed your aids, you should just leave them like that for a week or two. If then you feel something isn’t right, try using the Fitting Assistant for your first adjustments. It really beats taking wild guesses. Plus you get to see how the correction is being applied.

Keep us posted.

#41

Fred,

Sounds like good advice.

I have been tinkering with my programming for a couple of months now just trying out different things. Most recently I have turned on speech recovery. I have setup program 4 for bird watching and have boosted the high frequency bands quite a bit because a number of birds have calls that are too high frequency for me to hear. I am hoping that speech recovery might help with this by transposing the higher frequencies down to where I can hear them.

Just to clarify, I think it’s called Speech Rescue, not Speech Recovery. And you shouldn’t have to boost the amplification of the HF up because Speech Rescue should already transpose it down for you.

I find it quite helpful to have 2 programs side by side where one has Speech Rescue and the other does not so I can switch back and forth to confirm sounds that are transposed down or not.

And it’s not just bird calls but insect sounds and electronic beeps all of a sudden appear or if nowhere to me when it’s turned on. Real cool!

I haven’t looked closely at Speech Rescue, but just from a quick look at the fitting assistant that Joshua Alexander (Audiology Online, 20Q series on Frequency Lowering), it doesn’t look like Speech Rescue does what I would consider transposition. To me transposition would keep the musical relationship between notes. It looks like Speech Rescue just copies and pastes say 4000-5000hz down to 2000-3000hz whereas “transposition” (my sense) would halve it to 2000-2500hz. I know there’s more to Speech Rescue than that in that it also leaves the original frequencies in place and it splits them up into two or three sections, but mainly I’m interested in the musical relationship. A side note. I did I search on frequency lowering on this site and ran across some good discussions. One guy referenced a device made for bird watchers (listeners?) that transposes the bird song down. Gives the option for 1/2, 1/3 and 1/4. Their website has great examples.

#44

Oops, you are correct that it should be called Speech Rescue, not Speech Recovery.

That’s a good suggestion about having two programs - one with SR turned on and one with it off. I do have a music program as #3 which doesn’t use SR so I might use that as a comparison and see how it works.

As for birds, I agree that I am now hearing all kinds of high frequency sounds that I just couldn’t near before. The reason I kicked up the high frequencies on my bird program was so that I can hear not only bird calls that are very high frequency but also distant bird calls that are very faint. The problem is that it is hard to sort out the bird calls from any other sounds that are present - this only really works if I am in a very quiet environment (out in the woods) with little or no background sound. This is still a work in progress and I will be experimenting with the bird program for some time to come.

It’s not so much about musical relationship, but it’s about the natural selectivity of the cochlear. They don’t do it randomly or arbitrarily like you think. There’s definitely a science to their method of translation and composition. I think the goal by doing this is to minimize the distortion of the lowered signal. Below is an excerpt from their white paper that best describes it:

The specific Speech Rescue settings complement the natural frequency selectivity of the cochlea. The frequency selectivity is determined by the width of cochlear bandpass filters (auditory filters). Their widths, measured in ERB (equivalent rectangular bandwidth), increase approxi- mately logarithmically towards higher frequencies (the base of the cochlear). Following this natural perceptual arrangement, Speech Rescue captures several high-fre- quency bands and re-codes them in a lower-frequency band according to a logarithmic scale. Consequently, on a perceptual frequency axis the width of the destination regions (~ 3 ERB) is only a little smaller than the width of the source regions (4-5 ERB) (see log scale in Fig. 3b). This arrangement thus introduces minimal distortion of the lowered signal.

I have found an easy way to do some testing of the Speech Rescue feature. There is a web site that is just a tone generator that you can use to play back a tone at any frequency that you specify. The web site is here:

http://onlinetonegenerator.com/

I find that with Speech Rescue turned on I can hear tones in the range of 6,000 to 9,000 Hertz that I cannot hear at all with SR turned off. The tones that I hear are of course pitched at a lower frequency since they are being transposed by the Speed Rescue feature. I am currently using Speech Rescue setting #9 which seems to work fairly well for me but I need to try some others as was discussed previously by Volusiano.

I was surprised that the range of the Oticon OPN extends all the way up to 9,000 Hertz - that is considerably higher than my previous hearing aids could reach. I did try 10,000 Hertz but could not hear anything there so the upper limit must be somewhere around 9.000 Hertz.

Also try the hearing test portion of that same web site which is here:

http://onlinetonegenerator.com/hearingtest.html

This plays a sweep of frequencies from zero to as high as you can hear. I just tried it with SR turned on and as the frequencies swept up I could hear my aids transposing the upper frequencies - very cool…

This is consistent with what is in that table of the 10 configurations that I showed in one of the earlier posts in this thread. As you can see in there, the source frequencies of configuration 10 (the highest source band) is only up to the 9Khz range.

Thank you for the tone generator links, very interesting.

No aids - 4900
No SR - 6500
With SR - 11.000

Best proof of SR I’ve seen.

I’m impressed that you were able to hear sounds up to 11,000 Hertz.

What hearing aids are you using if I may ask?

#50

These are Phonak V90 312T which I have had from the beginning which was Sept '16.

Reading the comments below the tone generator was interesting. Some can hear very high pitches.

I found another interesting web site that can be used for testing the Speech Rescue function:

http://hearbirdsagain.com/sound-samples/

This one is a bit more down to earth, at least in my case since it is bird songs that are pitched at relatively high frequencies. Some of these birds I just can’t hear at all normally but now with my Oticon OPN aids and the Speech Rescue function I can hear all of them (but at lower frequencies, of course).

The web site is actually for a special device for bird watchers that does a similar thing by shifting high frequencies down to a lower range - that is why the recordings have several different parts where they shift the frequencies lower down. Thanks to my hearing aids I don’t need a device like that.
