Hmmm, many sounds I would now associate with childhood are sounds I only remember from childhood (growing up in the mid- to late 1970s). I doubt I’ll ever hear them again in life (and finding them on a recording somewhere would be pretty tough, though probably not impossible).
The sound of the channel changer on our old console TV. The kind you had to walk over and twist with your hand. Ka-chunk… Ka-chunk. You could even rotate the dial halfway between frequencies and get something weird on the screen.
Similarly, the sound of turning off that old console TV. The picture would quickly shink into a bright, tiny glowing dot in the center of the tube, along with an almost otherwise indescribable “zwwwippp” kind of sound.
The sound of putting a needle on a record. Yeah, if you’re an audiophile with one of those hydraulically descending automatic arm turntables, or just have a really soft touch, you wouldn’t hear it; but I was a kid with a portable 45 RPM record player. I do still hear this as it is sampled at the beginning of a song I have on my iPod “gym workout” playlist, Where It’s At by Beck. It brings me back every time.
The sound of a steam radiator hissing at night, with the heat pipes clanging occasionally. Sssssss-tink. Ssssss-tink. Glong-long-long-glongggg… tink. While my parents still live in the house I grew up in, they changed their heating system a few years ago so I no longer hear this. My own house (all of ten blocks away) is also steam heated, but it’s dead quiet. Guess they had some kind of leak all those years.
Those bong… bong… bong… tones I used to hear in department stores. The patterns would pause, and then repeat again. I think Cecil even wrote a column about them once, explaining how they were a kind of paging system used by the managers to summon/direct sales clerks to various places in the store. Now I guess they have wireless radios or cell phones.
Going a bit later to my teenage/young adult years, I get nostalgic for the sound of an impact printer: either a high speed dot matrix or a daisy wheel printer. In college, printing something on the laser printers cost 10 cents per page after a certain number of free pages (20 per week I think it was), so all draft copies were sent to the dot matrix printer in “draft mode”, which printed faster but with less resolution. The print head moved back and forth so fast the whole thing shook like it was fixing to take a walk. BZZZT-BZZZT! BZZZT-BZZT! And printing out computer code, which doesn’t take up a full page width with text for every line, would go even faster: BZZT-BZT-B-B-B-BZZZZZT! (Those lines with nothing but a curly brace would be the “B” sounding ones; the longer BZZZZT rows would be the code I annotated with a descriptive comment, well-trained programmer that I am.)
At an office I worked at they had a daisy-wheel printer that printed pages that looked like they’d been typed up in a typewriter. Because there was, in fact, a ball with typeset letters on it and an ink ribbon, just like an electric typewriter would have, and when printing it sounded like a machine gun firing. Rat-tat-tatatatatata-tat-at.
