I m not convinced that simple triangulation works in a city environment. Sound reflected off of buildings can mess things up good. I can think of several ways in which a later reflection can be louder than the initial sound.

Multipath interference can be mitigated to a large extent with multiple listening devices calibrated against a known acoustic impulse - i.e. intentionally firing something like a gun at a precise time & location known to the system beforehand.
