This sound is identified here as a strike cue from Australian Family Feud, the local version of the long running TV game show format. Short wrong answer sounds like this became popular far beyond television because they communicate failure in less than a second. Online, editors use them in meme cuts, trivia videos and streamer highlights whenever someone misses an easy point. It stays useful because the meaning is universal and the brief two-note shape cuts cleanly through dialogue without taking over the whole joke.
