Feedback or feedback loop is caused by the hearing aid picking you it own sound and re-amplify making the same sound louder than before. This got picked up again and re-amplify… until the speaker can no longer make it louder and saturate at some particular frequency.
Resonance has to do with the acoustic properties of your pinna, ear canal, ear drum and the receiver of hearing aid. This also has to do with the wavelength of the sound and the dimension of you ear canal. Lower Hz had longer wavelength that is longer the your ear canal and will not cause resonance. Higher Hz has shorter wavelength and cause resonance in you ear.
The issue here is the feedback loop, because it cause saturation of the receiver that distort ALL the sound from the receiver.
Shift/Compression/Transpose of Hz may (or may not) work for you. You have to try it at different setting AND it will sound different. There will be a learning curve. Of course its the best if you don’t need that and can hear the s/th after the hearing aid amplified it, but I doubt.
A spectrogram will show you more information of frequency & intensity of sound over time. If you can’t hear above 6k Hz, what difference does it make if I cut it off or not. You still hear the lower Hz. Most of the energy from the s/th sound is around 6k, if the hearing aid can move that to a lower, more audible Hz, you brain may be able to relearn that and map it to s/th after some training. CL
