Sound stopping

I’m trying to stop one sound that everyone can here in the game.
Which this is for my police siren,



local sound = false
local veh = ply:GetVehicle()
if sound then
			veh:EmitSound("vehicles/sgmcars/crownvic/siren.wav")
		else
			veh:StopSound("vehicles/sgmcars/crownvic/siren.wav")
		end


Theirs a function i just put some variables in their for you, also ply does exist.
Hope you can help.

Use CreateSound( veh, path ) for looping sounds. Then you can easily stop it.

Well know i fixed that part, thank you for the directions!
