Siren enthusiast here, it’s a surprisingly large community that’s really started to blow up these past few years. There are so many models and sounds that there’s always something interesting to find and I find them pleasant to listen to. Sirens are very powerful machines that move a ton of air, and they’re capable of shaking the ground and rumbling your chest when you’re near one. We have an annual Sirencon in Wisconsin every year where we bring our privately owned sirens (usually bought for cheap after they’ve been retired from service) and have a good time firing them up.
I personally enjoy learning the history of the sirens themselves and finding surviving units of rare historical models, especially those from between 1910-1950 when they were still trying to figure out what worked and what didn’t. There was a ton of innovation and cool designs. A lot of people associate sirens with air raids, but their original primary purpose was to replace bells, air horns and whistles at fire departments that needed an audible signal to summon volunteer firefighters to the station upon a fire call. Being electric, the siren didn’t need air pressure or steam which could run out, and couldn’t be confused with church bells.

I tested a military handcranked one once, it sure is a very special thing, the slow buildup, the sound and the wrrrrr vibrations.
Hand crank sirens are pretty fun! I’ve got one from China, an LK-100. It’s especially satisfying hearing the pops at low RPMs.
