️ Flow = Air/Time - If 1 liter of air is used and the phonation lasts for 5 seconds, the calculation is: - Average flow = 1 liter / 5 seconds - = 0.2 liters/second (or equivalent to 200 cc/second) - Note: Flow at a given instant may vary, meaning the average flow does not capture transient changes 
during phonation. ---
