These Are the Secret Sounds of All Your Electronics

By Eric Limer on at

We all know the telltale hum of a computer's fan kicking on, or the barely-there buzz of fluorescent lights. But even the most whisper-quiet devices are singing their little songs of daily life; you just can't hear them. At least not without some help.

Redditor TheDanielHolt took to uncovering some of these tuneless tunes, and while some are just a subtle buzz, others are far more dynamic than you might think. He describes his setup this way:

[I used] a 600D with kit lens, A Sony F-V5 mic, and a Mixer (Vivanco MX 800). The mic went into the mixer and the mixer was connected to the 600D's mic in port, essentially using the mixer as an extremely powerful pre-amp. Just to give you an idea of how powerful, the 600D was on the second lowest audio level.

It's a damn good thing we don't have to listen to this sort of stuff all the time, but it's definitely neat to hear the clamour our teched-up lives make around us, just beyond the reach of our puny human ears. [Reddit]
