How can i make sound play on custom range?ou

Make a song in workspace called Sound. Make sure it doesn't run at start and is Pitch 1.

I actually don't know, but... The best is to, make hidden parts, and put the sound into each player's PlayerGui using this simple localscript in StarterGui:

local Player = game:service('Players').LocalPlayer

local Song = game:service('Workspace'):findFirstChild('Sound'):Clone()
Song.Parent=Player.PlayerGui
Song:Play()

Now, this is the script (Normal one) you put inside the 'ghost walls' you made:

script.Parent.Touched:connect(function(part)
   if part.Parent:findFirstChild('Humanoid')~=nil then
   local Pl = game:service('Players'):GetPlayerFromCharacter(part.parent)
      if (Pl~=nil) then
        Pl.PlayerGui.Sound:Destroy()
      end
  end
end)

Hope this helps! If not tell output! If it helps and works please make this correct answer :333 ~marcoantoniosantos3
