there are some concrete examples of this though. we see the visible spectrum, a particular subset of EM spectrum that's a pretty good enough abstraction to get around in the world, it's a heuristic for the spectrum that's "good enough". we hear a subset of the audio spectrum, it's "good enough". etc etc...

Knock on the walls, scream and see if anyone hears you, listen for sounds through the walls, if you do this for enough houses before you got a chance to open the door and walk around you might be able to make order of magnitude estimates. Always assume the house is bigger than you think.
