Hi guys!
I lately discovere the Neutralizer app for Android (https://play.google.com/store/apps/details?id=eu.javeo.android.neutralizer). I find the concept very good and had very nice results with my KSE1500. It basically generates tones in different frequencies (125hz, 250hz, 2khz and so on) and you adjust the EQ until you barely hear the tone. By that you get an EQ profile based on your actual hearing (headphone + own hearing capabilites).
But I find the app lacking more frequencies as IEMs can have adventurous FRs, especially in the highs. Therefore I wanted to replicate that idea on my PC by using a simple tone generator like this (https://www.szynalski.com/tone-generator/) and Equalizer APO. Then playing a tone e.g. 2000KHZ and adjusting it via Equalizer APO so that I can barely hear it. I would then repeat that for the frequencies I would like to.
That was the idea, but I end up having huge differences in volume for different tones, e.g. I need 15DB+ for 20hz while 4KHZ is at 0. So I assume the tones should not have the same loudness for this purpose? Is there a formula how I can calcualte how loud each tone needs to have for this purpose? Or am I doing something completely wrong?
Any help would be appreciated!
