how to make the sound sounds like its in a house if player is outside?

I am trying to make the music sounds like its inside a house if player is outside it

The only thing i know is that the reverb is changeable, but I have no idea how to make that reverb thing,

I've seen this on a game called Club RAVEN https://www.roblox.com/games/1105449649/

I can do this:

function onTouched(hit)
game.SoundService.AmbientReverb = "Underwater"
end
wait (1)
script.Parent.Touched:connect(onTouched)

Please give me some help I would really appreciate that (:

Here's my answer. To actually create something like that you have to have it coming out from a block or part. I suggest inserting a sound, then repeat the sound. I hope this helped.
