That modem sequence is probably one of the most memorable pieces of a whole generation's childhood. If you ask me now, when it's been over two decades since I've heard it, I would easily be able to badly reproduce the whole 30 second soundbite with my voice from memory. With confidence I could probably nail every single beep and boop including the pauses between them and the odd static sound near the end of the whole process.
I used to invite mates over and move my hand like a wizard to change the frequency of the tones, not letting on that I'd memorised the whole sound sequence by rote and was messing with them.
Honestly, all the silence has made me more wary of computer temperatures.
I never used to be able to hear the fans, but now that everything is solid state, they're the one constant. And it worries me occasionally when they kick on for no discernable reason.
Silence is nice too though.
