Post updated with answer and winner.

Chances are you’ve heard this sound before. But can you identify it out of context?

The latest installment of our Name that Tech Tune challenge is one of those deceptively simple ones, and it has the potential to fool you — although it’s not nearly as tricky as our previous challenge. (Sorry folks, but that was Ernie, not Kermit, singing that Sesame Street song.)

Up for grabs this week is a pair of tickets to the GeekWire Summer Bash, coming up June 21 at the Showbox Sodo in Seattle. From the pool of correct answers, we’ll pick one person at random to win the tickets.

Here’s the sound. What is it? If you know the answer, send it to contest@geekwire.com.

Name that Tech Tune is a regular feature of the GeekWire radio show and podcast, airing at 7 a.m. Saturday and 1 p.m. Sunday on 97.3 KIRO-FM in Seattle, and running weekends on GeekWire.com.

If you’re stumped, we give a couple of hints in the Tech Tune segment on this week’s show.

Send your entry to contest@geekwire.com.

Look or listen for the answer next week, and thanks for playing!

Update, May 25: The answer, as a lot of you knew, was the sound of an incoming message on Facebook. Congrats to our winner, Whitney Moore.
