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)
