I need help with my drowning sound script

[Galton]

hello, I'm new to scripting and I want to make a drowning sound script, my code works fine but I want the sound to play only once, how can I do it?

here's the code;

function drowning() getPedOxygenLevel ( localPlayer ) 
local oxygen = getPedOxygenLevel ( localPlayer ) 
if oxygen == 0 then 
    local sound = playSound("sounds/drowning_sound.mp3") 
    setSoundVolume (sound, 3.5) 
    end 
end  
  
addEventHandler("onClientPlayerDamage", getLocalPlayer(), drowning) 

[.:HyPeX:.]

function drowning() getPedOxygenLevel ( localPlayer ) 
local oxygen = getPedOxygenLevel ( localPlayer ) 
if oxygen == 0 then 
if not sounding then 
 local sound = playSound("sounds/drowning_sound.mp3",false) 
 setSoundVolume (sound, 3.5) 
 sounding = true 
 setTimer(function() sounding  = nil end, 3000,1) 
end 
    end 
end  
  
addEventHandler("onClientPlayerDamage", getLocalPlayer(), drowning) 
  

Btw, the first lina is wrong, or at least weird... (Or you copied the code over badly)
