The other day, a friend sent me a link to a Reddit conversation: What common sounds from a hundred years ago are very rare or just plain don’t exist anymore?
This, in turn, led us to the Museum of Endangered Sounds, which I highly recommend to anyone with a pair of headphones and a few hours to kill. Of course, we can’t even document some of them—the early-morning scuttle of coal, for instance, was probably too humble ever to rate a recording. I mean, how many of us have bothered to record the hiss of a radiator—and presumably that won’t be around forever. For that matter, someone ought to memorialize the rattle of a dead, incandescent bulb.
I must have had this in mind when I ran across this image on Retronaut. Because the sound of a card catalog—the squeak of the drawer, the slight ruffle of the stiff paper, the sliding noise as a card is pulled from the file—is almost certainly on the endangered list. (To say nothing of everything else in the picture.)
