Where have all the sound effects gone?

New York Times' David Pogue blogs today about cultural artifacts of obsolete technology, specifically, cartoon sound effects:

What about the needle-scratching-across-the-vinyl-record sound? It’s still used everywhere, in cartoons, movies and so on, to represent a rude awakening, an abrupt interruption of a scene’s mood or the main character’s reverie. But today’s children have never even seen a record player. Isn’t the record-scratch sound totally lost on them?

And what about “ka-CHING!”? Cash registers don’t go ka-CHING anymore–they go beep!

I'd add to that the whole notion of "dialing" someone's phone number on your cell phone.
