Yesterday, I went searching for the school district’s web page to see if they had posted a school cancellation notice. There was nothing yet, but there was a list of places where cancellation information could be found — radio stations, TV stations, and so forth. Apparently, the fire station also rings its bell in a certain pattern at 6:30 and 7:00 a.m. to signal weather-related school changes: two dongs for two hours late, four dongs for no school. I had not been aware of the fire bell code.

The late news did not report that the school district was closed, but at 6:30 the next morning I was awakened by four bells, saving me the trouble of sitting through the display of 400 school closings until they got to the Ns.

I was charmed by this display of analog non-verbal mass communication, and I tried to think of some other modern-day examples. Here’s what I came up with:

  • Emergency sirens
  • Clock chimes
  • Call to prayer
  • Skyscraper lights that indicate weather changes

With the prevalence of electronic networks, this type of communication might be dying out. Any other examples?
