Delta Values
So this feature is called Delta Values, and this is working in the REM module.
The Delta Value feature gives you the difference between your measurement curve and your target curve, allowing you to get a better target match when fitting hearing aids.
Because the system is calculating this for you, it allows you to alter the gain trimmers in your fitting software much easier, so that then we are getting a better match to target.
Let's have a look at how this is working now.
So here in the software, we can see that I have an existing measurement curve in relation to the target.
Typically I would eyeball this for Martin here and see the difference between the measurement curve and the target curve.
However, to fit his hearing aid, I would then need to alter the gain trimmers to make this match.
But by turning this feature on to the left, it actually tells me the difference between my measurement curve and my target curve.
Meaning that it makes it easier for me when I am fine-tuning.
So let's go ahead and fine tune this hearing aid now to get a target match.
So let's run a second measurement and see how well we've matched our target.
Okay, so that's a much better target match than before.
And we can run it at the softer and louder intensities where the feature will also give us the same readouts of the delta difference.
So the Delta Value function works both in the insertion gain view as we have worked with in this example.
But also for the aided responce measurements, so you can see the patient's threshold and uncomfortable loudness level, as well as your measurement and target together.
That helps to keep things together in the same view when working with fitting.
And it also works in the visible speech mapping view too.
Thank you for taking the time to watch this video.
