The PBS gaming sound test is more of a trip down an audible memory lane than an actual test, at least for 30-somethings and older. I got an 18 out of 18, but I almost missed one or two.

Wow, that Galaga sound is embedded in my brain. I swear to God I almost started pounding the desk in front of me with two fingers when I heard it.
