This isn't as much an air raid siren as much as it is a siren on a fire truck

[@Bread_stick06]

how do tornado sirens work tho wut makes the sound

[@B4sh3rk77]

TThe air going through the holes. The air makes a loud sound. When it spins fast enough, Or if its just a electric one. that uses speakers.
Which this one isnt,

[@Alkatross]

The square holes in the shroud create the sound as the fan blade passes by them. A pulse is heard as the air pressurized by the fan is pushed through the hole. When the air is being blocked by the ring, we perceive a period of rarified air pressure, and when the air is released through the holes we perceive a period of compressed air. The difference between these period is measured over time as a pitch. The faster it spins the higher the pressure being made by the fan so the louder the sound. The pitch also increases with the speed.
