Hello
I'm a 41 yo man who is hard of hearing from birth. See my pro curves:

I've tried Earful in order to make a Hi-Res audiogramme for test and seems to be quiet different :
( I have to say I don't really understood how to calibrate the hardware )

There is a bug about simultaneous curves display:
Right mode data set 1:

Left data set 1:

I made this test with windows 11 laptop, Fiio Q3 DAC/AMP, IEMs ER2SE Studio, 3.5mm asymetric output and custom tips.
Can someone please explain me how I have to do in order to calibrate the hardware ? I have a tiny brain...
In order to calibrate the hardware, you'll need to use a calibration curve created specifically for it, usually measured on some standardized equipment. It may still not match your audiology exam results, since we don't know what curve was used to calibrate that device. In general, it's nearly impossible to compare results produced using calibration curves created using different calibration devices, as each device has a different response target. The best you can do is compare two results from the same equipment with the same calibration curve. Some standardized calibration curves exist, for example, here: https://github.com/jaakkopasanen/AutoEq/tree/master/measurements
But these are, again, not something you could compare directly to your audiology exam, since that was using a different calibration hardware.
Without a hardware calibration, Earful gives you is the actual audibility thresholds with the IEMs you are using in combination with your hearing. In other words, what you are likely to be able to hear when using these IEMs when playing music or listening to voice.
