CULTURE/SOCIETY - 11 Sounds That Your Kids Have Probably Never Heard

Who knew that some noises could eventually become as extinct as the passenger pigeon? Depending on your age, you or your kids or grandchildren may have only heard some of the following sounds in old movies, if at all.

1. ROTARY DIAL TELEPHONE

The formerly familiar swooosh as the caller rotated the dial clockwise to the "finger stop" and then the click-click-click as the dial returned counter-clockwise to the start position is now a novelty application that you can install on your iPhones for nostalgic yuks. Adolescents waiting in line nearby will wonder what the heck that sound is, while we older fogies will know you're poking fun at us and our ancient ways.

2. MANUAL TYPEWRITER

Manual typewriters had an entire subset of unique sounds that made them immediately identifiable...at one time. The keys clacked loudly as they struck the paper, the carriage lifted up with a distinct clunk when the shift key was employed, and then there was the ping of the bell warning you that you were nearing the end of the line. That meant you had to lift your left hand from the keyboard and swipe at the carriage return lever, which caused a sort of ziiiiip noise as you pushed the carriage back to the starting position.

6. RECORD CHANGER

Record changers allowed you to stack a selection of albums of 45s (seven-inch singles, not guns!) for your longer-term listening pleasure. Each record would make a soft slap sound as it dropped onto the turntable, a series of clicks followed as the remaining records adjusted into place and the tone arm swung over and lowered the needle into the outer grooves of the record. You'd hear the slightest scritch noise as the stylus settled just so into the vinyl and then (finally!) the music began.

10. FILM PROJECTOR

One of the jobs of the classroom A/V squad captain was to run the film projector on movie days. The rapid tick-tick-tick of the sprockets really was that loud and usually accompanied by shouts of "Turn it up!" and, of course, "Focus!"

11. BROKEN RECORD

Remember when you'd beg mom over and over for something and she'd finally yell, "You sound like a broken record!"? She wasn't referring to pops or hisses, but the repetitive effect that happened when the needle got stuck and played the same few notes over and over and over again.

If you're not afraid of revealing your true age, let us know how many of these you remember from your past!
