Trying to make it when a player is inside a invisible block all sounds have echo effect?

I can't figure out how to have it when the player is inside the part for it to become echoing with sound service I can although make it echo but not with when the block is touching

This is what I have to make it echo but not when it is being touched

game.SoundService.DistanceFactor = 99999

game.SoundService.DopplerScale = 99999

game.SoundService.AmbientReverb = 9

game.SoundService.AmbientReverb = "ConcertHall"
