SodaStream Fizzi Carbonation Sounds

I've used the SodaStream Fountain Jet before (the Fizzi replaces it as the entry-level machine) and I HATED the "loud buzz" sound it makes to tell you the water is carbonated. It sounded like a demonic fart. I picked up the Fizzi, and while the bubbling sounds are the same, the buzz is replaced by a much less embarrassing puff! This is a quick video of me carbonating some water until the machine puffs twice.
