Test of siren in Argentina

[Daniel]

I'm not sure how these men could stand so close without hearing protection.

I am guessing they have a very good tolerance to loud noise. Talk about getting personal when testing a large siren!

Well it's a siren... But these people are Argentine, they are wild people! I don't think they really care for their hearing! Anyways, sounds pretty normal, especially for a 2800RPM siren. But the housing is pretty wacky.

That is an eight-port, single-speed siren. Many Argentine sirens are twelve-port sirens with two-speed motors, copied from WWII Italian models, which make a kind of slow wail by slowly alternating between speeds.
