sometimes, my job is actually interesting

'cos today I was tasked with carrying out sound pressure measurements on a couple of these. first time I've actually held a siren of any substantial size in my hands. Loud SOBs, that's for sure

It seems as though mechanical vehicle sirens are making a comeback. First the Timber Wolf, now this! Cool beans!

Seems they could be even louder if the stator ports weren't so covered up by the chrome collar with small angled slots.
They don't indictate from how many feet away they get 124 db.
That's an important omission.
Thanks for the photos.

probably, but then you'd have a safety issue.

Thanks for the photos.

can't take credit, those are from the company web site. I work for a test lab. I might see if I can post a couple of the photos I took, though.
