I really struggle to process voices, but I hear absolutely everything.

Someone talking to me can get completely drowned out by a 15KHz hum of an electronic device, the acoustics of a room or a TV in the background.

Yet, I ask them if they are having trouble hearing me over all the noise. They usually reply “wharlt noise?” If it’s a high-pitch hum, they won’t acknowledge the noise even if I show them on a spectral analyser.
