   you should hear the new sirens they're using and testing in various locales   
   here... i was in Raleigh the other day and had occasion to hear them when the   
   gendarmes came by on the way to assist the firetrucks... i can't describe the   
   sound of them, though... they have a bass note to them and you can actually   
   feel them when they sound... i think they call them the "rumbler"... you can   
   hear it at 0:05, 1:16 and 1:28 in this link...

   very strange sound... i was surprised to hear them in real life... i had heard   
   them in the TV series Colony and didn't know they were for real...
