What you’re looking for is occlusion and obstruction, as well as early reflections management.
There’s nothing like it in UE4 at the moment, nor most game engines - the way it’s managed usually consists in placing reverb or obstruction volumes which may or may not be extracted from the geometry (it’s usually done manually).
There are a few projects to handle this sort of things automatically, such as Two Big Ears’s. I haven’t tried it personally, it’s in closed beta at the moment, but you can apply for it.
