• The world's quietest room

    MPR News has an article about a room in Minneapolis which is officially the world's quietest. Known as an anechoic chamber (a room that has no echoes), it has been measured at -9 decibels.

    The article includes an interesting audio segment that goes into some detail about how and why the room exists. Of note is the fact that many people experience discomfort and disorientation in the absence of normal ambient sound.

    Unfortunately the audio player leaves a few things to be desired, at least in the browser I used (Chrome). No playback controls, no way to know how far through the clip you are, and a non-functioning level control. I didn't time the piece but I'm guessing it was about 10 minutes long.
