Comments on: Broadmoor Civil Defense Siren full view
Reader comments and feedback for the Broadmoor Civil Defense Siren full view photo.
This image is part of the Historic Photos photo gallery http://www.shreveport.com/forums/pho...b6497bf9_l.jpg Civil Defense Siren , located on Akard Avenue (between Atlantic and Pennsylvania Aves.), on the East side of Broadmoor Junior High property. (4/2005)<br /> <br /> Tested every Saturday at noon. Loud. Though I never was next to it when it went off, it could be heard all over Broadmoor, South Highlands and probably beyond.<br /> <br /> Appears to be a Thunderbolt 1000 series.<br /> <br /> Pictures and sounds here<br /> http://www.civildefensemuseum.com/sirens.html<br /> http://en.wikipedia.org/wiki/Civil_defense_siren<br /> |
Maybe someone can describe how the actual tone sounded. I don't recall if it was a single steady tone or whatever.

I-S, the specs for the Thunderbolt 1000 say it outputs 125 dB measured at 100 ft.
Also for perspective, the cone is 56" long and the opening ~28"x29". I think there used to be one on top of a building downtown. Wonder where others were located? |

This thing used to rotate. I lived two blocks north of Broadmoor School and it would get really loud and then start to fade. All of a sudden kids would start coming outside and start playing after this. It signalled the end of cartoons on Saturday.

Speaking of riding a bike. This same time period, we would be riding along and the mosquito trucks would come by. We would ride behind them untill the smell hit us and then it was all we could do to not fall off our bikes. I'm still waiting to get cancer from that. Maybe I'm not waiting anymore, who knows.

LOL -yeah. The trucks always came by our area at dusk or late at night. And anyone remember the WWII surplus aircraft (pretty sure it was a B-25/24? I knew exactly what it was at the time but memory fades) tricked out to fly treetop level practically and spray for fire ants? I recall them flying over VERY low in South Highland area. Google Note: found a citation that said WWII aircraft were routinely used to apply mirex bait 1962-1978 timeframe (states got matching federal $ in the program). Before that it was granular dieldrin or heptachlor. They don't sound like good things to drop on people. A lot of good it did too -those buggers are chewing my ass up all the way up here in the Carolinas today. Quote:
Of course - doh! reading about this model of siren learned it didn't vary in pitch so I couldn't figure why my memory had it changing - it was cause it rotated - completely overlooked that obvious point. Thanks purpahurl :beerchug: ... and nice memory shared too :) |
I think the horn produced a steady tone, but it gave the impression of an up and down tone as the horn rotated around. It seemed to take about 30 to 45 seconds to complete one turn around.

Seriously this is how I remember it. I lived about a mile from Broadmoor. The dogs all over would go nuts howling at the siren... Especially our dachshunds. |
