How do sirens work
Bit of a weird question, but how do (real) sirens work? I work IFT, and the sirens we have are more like speakers. When I flip them off, they shut straight off. They also aren’t as loud. The 911 ambulances I hear running around sound more like “real” sirens. When they’re turned off, they still have to slowly wind down. I know some vehicles use foot pedals for the air horns. Is it similar to that?
