At certain times I can hear certain noises others cant.
electric, gas burners whistling, water taps hissing, vibration along power cords.
At other times I believe it's inside my own body.
I appear to have a symphony going on.
Tinnitus, carotid artery, various creaks, snap, crackle, pop, grind and thunk of joints and vertebrae and the loudest of all, palpitations.
I'm capable of occasionally associating sounds with certain actions, for example,
feeding the cats.
I follow the same routine or pattern, I expect the cats to do the same thing they've always done,
So when I 'hear' the cat pawing at the door to be let into the room to eat her food,
and I open the door to discover
no cat, just empty space.
I've imagined I could hear her because our process/routine has followed the same pattern each day for 11 years. At a certain point in our routine she paws at the door like clockwork.

largely noticeable due to its absence.
