1. A computer-implemented method for determining an acoustic model of a room within a building for use in an acoustic real-time locating system, the method comprising:
transmitting an acoustic signal from a static acoustic transmitting device;
receiving, at the static acoustic transmitting device, reflected signals resulting from interactions of the acoustic signal with structures forming the room;
receiving a location and orientation of a static acoustic transmitting device; and
forming the acoustic model based on the reflected signals and the location and orientation of the static acoustic transmitting device, wherein the forming the acoustic model further includes alias mixing the reflected signals.
