Question, how do you make audio sound like it's in a hallway?

Currently trying to make sounds for an immersive audio of walking down a hallway and entering a room where the audio's coming from. The audio is a couple of guys singing while cooking.

I believe a combination of reverb and a fade in might do the trick.

The reverb might not suit so discard that. Fade in is must here
