I’m curious, can you hear electronics? I can hear a CRT TV from almost 100ft away (the TV being muted, of course) and can tell you when it’s off and on without seeing it (it used to be a fun party trick back in the day). I can also hear capacitors in general if I try (but I just tune it out or I would go insane).

Those “how old is your hearing” sites peg me at 14 though I’m actually double the age and then some.
