Different sound plays when somebody else touches a brick with sound script?

Sorry if the title doesn't make sense, but how do I change it so that when the player touches a brick it plays sound without others interrupting? Like when guy A touches a brick that has this script, it plays a sound, but when guy B touches another brick that also has this script with a different sound, the sound for guy A changes too to that sound. How can I fix that? Sorry if this sounds like a piece of cake.

guy A's touched brick:

 local debounce = false
 script.Parent.Touched:Connect(function()
 if not debounce then
 debounce = true
 		workspace.SoundA:Play()
 end
 end)

guy B's touched brick:

local debounce = false
script.Parent.Touched:Connect(function()
if not debounce then
debounce = true
		workspace.SoundA:Stop()
		workspace.SoundB: Play()
end
end)

I want it so that the player only gets to hear the sound when they only touch the bricks themselves.
