It's time once again for your weekly "Name That Noise" episode - every Tuesday we present a new mystery sound from the world of technology, geek culture (video games, science fiction), or some other random noise from around the world that you're likely to recognize.
This week's sound should be relatively simple for techies - in fact, you get bonus points if you can identify multiple machines from which this sound may come from.
