How do I make a sound play when a gun on a plane shoots?

So i made a plane using a kit, when a gun shoots it doesn't make a sound. So when you enter the plane there's a tool that opens up the HUD, there's a local script and i found with a function that makes the gun fire, so i need help cause i dunno what to type in and where: (also i already put the sound in the tool)

``function FireMachineGun(GunParent)

--This function creates the bullets for the MachineGuns

while FiringGun do

	for _,v in pairs(GunParent:GetChildren()) do --This is what allow you to put as many MachineGuns as you want in the Guns folder

		if v:IsA("BasePart") then

			if v.Name == "MachineGun" then

				local Part = Instance.new("Part")

				Part.BrickColor = BrickColor.new("Bright yellow")

				Part.Name = "Bullet"

				Part.CanCollide = false

				Part.FormFactor = "Symmetric"

				Part.Size = Vector3.new(5,5,3)

				Part.BottomSurface = "Smooth"

				Part.TopSurface = "Smooth"

				local Mesh = Instance.new("BlockMesh")

				Mesh.Parent = Part

				Mesh.Scale = Vector3.new(1/12.5,1/12.5,1)

				local BV = Instance.new("BodyVelocity")

				BV.Parent = Part

				BV.maxForce = HugeVector

				local PlaneTag = Instance.new("ObjectValue")

				PlaneTag.Parent = Part

				PlaneTag.Name = "PlaneTag"

				PlaneTag.Value = Plane

				Part.Touched:connect(function(Object) --This lets me call the "Touched" function, which means I don't need an external script

					if IsIgnored(Object) then return end

					if (not Object:IsDescendantOf(Character)) then

						local HitHumanoid = Object.Parent:findFirstChild("Humanoid")

						if HitHumanoid then

							HitHumanoid:TakeDamage(100) --This only damges the player if they don't have a forcefield

							local CreatorTag = Instance.new("ObjectValue")

							CreatorTag.Name = "creator"

							CreatorTag.Value = Player

							CreatorTag.Parent = HitHumanoid

							delay(0.1,function() CreatorTag:Destroy() end)

						elseif (not HitHumanoid) then

							Object:BreakJoints()

						end

						CreateShockwave(Part.Position,5)

					end
				end)
				Part.Parent = game.Workspace
				Part.CFrame = v.CFrame + v.CFrame.lookVector * 10
				BV.velocity = (v.Velocity) + (Part.CFrame.lookVector * 2e3) + (Vector3.new(0,0.15,0))
				delay(2,function() Part:Destroy() end)
				table.insert(IgnoreTable,Part)
			end
		end
	end
	wait(GunTime2)
end
