I’ve heard this before, but I still take psychic damage every time I hear it

Not to double reblog, but this would be an interesting application to nuclear semiotics. If this sound could be preserved and serve as a proximity alarm for places that aren’t meant to be disturbed, how well would that work?

I mean I absolutely wouldn’t go near any weird structures just blaring this.

This is not a broken tornado sirin. This is a full on tornado warning sirin. The pattern is called an alternating wail. It has begun to be utilized for Two reaons. One, the normal key up sirin holds a note, and backs off slowly. If you are headphoned or doing loud work it can be hard to hear. Two, hollywood has desensitised us to the origanal sirin. It is offputting and loud, but does not create the sense of urgency needed durring an emergency.

the alternating wail was designed with a spin up and spin down, and half octive jumps timed diffrently then the patern of the primary wail. It is just off enough that it instantly makes you feel unease and danger.

Which is what its designed to warn about!
