What is the loudest air raid siren ever made?
It is the 180HP V8-Hemi engine powered Chrysler Air Raid Siren, 138 dB @ 100 feet. 3. What is the loudest air raid siren currently made? It is the American Signal T-135, a 50HP uni-directional siren capable of 135 dB @ 100 feet. 4. Where can I get my own electric air raid siren? I have three suggestions. The first two are for collectors/enthusiasts, and the last is for those of you looking for an affordable used siren for installation in active fire or tornado warning service. Ebay is one place to look, but these sirens do not show up that often, perhaps there are a handful each year. The Federal Model 2 and 2T show up most often, and generally sell from $400 to $750 depending on condition an what is included (housing, timer, starter, etc…). Larger sirens are usually much cheaper because nobody can afford to move them so they get only local interest. You can usually score a 3 to 10 horsepower siren for $100-$300, but you need to be able to go get it because they’re all at least 300 p
