Where do I insert debounce into my script so the part wont trigger the function multiple times?

Lets say I have 2 parts. Front, and FrontDamaged. My script makes Front transparent, and FrontDamaged not transparent, whenever Front touches another part. It also plays a sound when it touches something. The thing is, it has no cooldown. And im stuck on where to add the debounce at.

local Front = script.Parent.Front
local FrontDamaged = script.Parent.FrontDamaged
local sound = script.Parent.Crash
local debounce = false


if not sound.IsLoaded then
	sound.Loaded:wait()
end

local function onPartTouched(otherPart)
	print(Front.Name .. " has touched " .. otherPart.Name)
	Front.Transparency = 1
	FrontDamaged.Transparency = 0
	sound:Play()
	
end
 
Front.Touched:Connect(onPartTouched)

TLDR: I need help putting a debounce so the part wont touch stuff multiple times at once.
