Target diagram two gain curves, REM?

Target.pdf (268.5 KB)

There are 3 gain curves, 50,65 and 80 . I would like to know why I have 2 red curves for each gain level in my graph. One is the fine line” called target gain” at e.g. 65 dB. The thicker red line seems to be actual gain.

I have enclosed the graph.

My guess is that the target curve is from a once made to the hearing aid. If that is so, I guess I should try to close the gap betwen the two curves for each dB curve. Is the target curve result of a REM made a few years ago?

As you can see, in my recent graph, the target gain is below the actual. Could that be because the REM was made a few years ago and my hearing has changed? Is the conclusion then that i have no use of the old REM curves?

Thanks for any advice

You nailed it. If you put your mouse on one of the lines, an info message will appear explaining what the point/line is.

The way it works
(1) is entered in the software.
(2) Feedback calibration is done.
(3) Formula selection is done (and this creates the thin lines)
(4) Run and modify gains to ensure the prescribe levels are reaching the eardrum correctly
(5) Additional gain changes to fix issues.

Thick curves don’t change automatically. They simply reflect the manual adjustments after the automatic formula fitting occurs.

Thanks Ocram, very useful information!

Please just let me try to explain to my self to make sure I have understood :smiling_face:

Thin lines calculation by the software based on and formula selection. Thick lines based on automatic adjustments by feedback calibration and manual adjustments. So, obviously, my ears needed more gain than forseen by the formula.

So I started some years ago with a wich was set by my Audie. She also made a and selected formula APD2.0. That original diagram also has two sets of curves. I presume the thick manual setting curve at that time was based on the audie adjusting to fit the REM.
Before starting to use Target I saved the audies original settings.

I now have entered a new audiogram in the Traget software, made a new feedback calibration and let the program recalculate. I suppose that the feedback recalculation is done with the original audie settings as a basis. They will remain until I make a new session.

So Ocram, have i understood your lesson :grin: ?

While I have your attention, is there anything you can see in my diagram that you would like to comment, suggestions?
