How to make something sound like it's coming from outside?

Hi everyone. I’m currently working on creating the sound effects for a show my college theatre group is doing, and I’ve run into a bit of a puzzle trying to make the rain sound like it’s coming from outside using Audacity. I’ve tried fiddling with EQs, but I just can’t seem to get it to feel “right”. Does anybody have any suggestions?

Thanks in advance,

Roll off the treble so that it sounds a bit muffled.

It will sound more authentic if you can make a contrast with rain outside and provide theatrical clues - for example:
Door opens - rain sound.
Enter John, dripping wet.
Door closes - muffled rain sound quieter.
John: “Oh it’s filthy weather out there”, hanging his coat by the fire.

Thanks for the quick reply. The theatrical cues have already been taken care of in the script - the characters are talking about the storm approaching for several scenes.
