Minneapolis overhauls network of emergency warning sirens

Body: 

Minneapolis is in the process of replacing each of its 30 existing emergency sirens and adding 12 more in a complete overhaul of its emergency warning system.

The first phase of the project is expected to be operational by Jan. 1, but it only addresses sirens outside of Downtown.

Bruel and Kjaer, a Danish sound engineering company, is finishing up a 3D mapping study of Downtown that will be used to in conjunction with an acoustic software program to determine how to redo Downtown's emergency warning system. That project will probably not be finished until later in 2014.
