A thing can be noisy or quiet. A thing is usually quiet.
Every turn when the player is not in the car:
if listening:
make no decision;
call the swift rule on everything in scope;
let noisemaker be a random noisy marked for listing thing;
now everything is not marked for listing;
if the noisemaker is something and the noisemaker is not in a closed container:
try listening to the noisemaker.
Report listening to a quiet thing:
say "[The noun] [one of]do[es]n't make much noise[or][is-are] naturally silent[or]make[s] no notable noises[at random]." instead.
Report listening to a person:
if the noun is the current interlocutor:
say "I'm paying attention, don't worry." instead;
otherwise:
say "[You] hear some breathing, I guess. Nothing extraordinary." instead.
