We found a list online of sounds you'll probably never hear again, and some are pretty recent . . . although the sound of a modem connecting DOES feel like it was 100 years ago.

Anyway, here are nine sounds that are either extinct or so rare today that they might as well be . . .


1. A factory whistle starting or ending a shift.


2. A mechanical cash register.


3. A steam locomotive.


4. A car backfiring.


5. A dial-up modem.


6. TV static.


7. A busy signal.


8. A pager.


9. A fax machine. (Reddit)
