9 Sounds That Have Disappeared or Will Soon

We found a list on Reddit 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.
