Here is a little known fact about the use of sound during the second World War. By that, I mean I didn't know it!
To tell the truth, this was a brilliant use of the loudspeakers to keep the public informed. I would have never thought of it, I'm afraid!
Radio was an incredibly important form of mass communication during World War II. For example, before and after air raids, the city of Leningrad broadcast instructions to take cover and later, issued the all-clear over a municipal radio service. That radio system reached most of the city; it had about half a million households and businesses with speakers, and another 10 to 20, 000 loudspeakers on the street. But what if the Germans bombed the transmitters? How would the people of Leningrad know? To account for this, the city radio employed an early version of comfort noise, softly broadcasting the sound of a metronome when no announcements were being made.
Just goes to show that folks can come up with some ingenious ways to stay alive and help others do the same. Pretty cool!
Coffee out on the patio this morning. Fresh peaches on the side!
