Gunshots wake guards on the other side of a wall that no sound could pass

A shot goes off and every enemy within a circle turns around, including the ones in a sealed room next door. Here is how to let sound follow the corridors, get dulled by doors, and fade out, so only the guards that could hear it react.

Why this works

Sound does not fly through stone, it finds its way along openings and loses strength as it goes. Treating loudness as an amount that is used up along the route lets doors dull it and walls stop it, so only guards who could really hear it react.

When not to use it

Skip it in games with thin walls, open fields or vents, where sound should carry straight through, or when the player wants a simple, readable rule. A plain circle is easier to explain, and players can learn to predict it.
