Does it matter for the volume of a sound which of the two doors it’s travelling through is closed?

Imagine this situation: Three rooms in a row, each one connected by a door to the next one. Room 1 has something that makes a loud noise, e.g. a washing machine. I’m standing in room 3 listening. In one situation, the door between rooms 1 and 2 is closed, while the door between 2 and 3 is open. The other situation it’s the other way round.

Does it make a difference which door is open for the volume of the sound I’m hearing? Why (not)?

In any real life situation, there are going to be too many variables to say. In a “vacuum” where the rooms are perfectly constructed and symmetrical and ideal, it shouldn’t matter.

“Vacuum” as in an unrealistic setting for a scientific hypothetical, not literally a vacuum.

In real life, you have tons of things affecting the acoustics. The biggest thing would probably end up being whether one door sealed better than the other. But besides that, you have the shape of the rooms, the furnishing, the flooring, even what the walls are made of, the location of the source of the noise, etc.
