How sirens and alarms work?

361 views

Is the sound of the siren or alarm designed to create that rush of adrenaline or danger that we feel? If so, how do they produce that response? Or do we just feel that way because we associate sirens with danger?

I have a theory about this. Not long after having kids, it became apparent to be that a baby’s wail / gasp for breath / wail has the same cadence as most sirens.

It’s only a guess, but I suspect that early sirens were modified until they became attention grabbing, and it happened to be a sound vaguely similar to a giant distressed human baby.

Just a random thought though.
