Sound Defect

Dennis Hartin e-mails:
Every so often, I hear a commercial that uses a sound effect to announce a 180-degree turn in the discourse, as in, "Sure, we're selling cars with 0% financing, but now...[sfx]...you pay no money down!" The sound effect used is the sound of a needle being shoved across a vinyl record. I know vinyl is making a comeback, but I suspect many of the people hearing that commercial have never actually heard a needle being shoved across a vinyl record. I wonder what they think the sound is.
That's a good point. The commercial was likely produced by someone over 40, for whom vinyl records were once a daily reality. But to my daughter's generation, it's as irrelevant as the sound of tape rewinding. Or a busy signal.
