In my bedroom in Copenhagen the radiator was ticking all night in the winters. It was very confusing at first and very comforting at last.
I recorded the sound through a whole night before I moved out.
When I hear it again I am in that space immediately.

What is the voice of the space you’re in?
Turn off the light or close your eyes for a minute or two.
Anything?

Perhaps the sound is not there all the time, you might have to provoke it a bit.
Like the squeak in the door or the floor.

Open the sound recorder on your phone.
Record the sound you found.
There might be several. Get them all.
Hold on to the recording, we’ll come back to it later.
