16. A computing system comprising:
one or more processors; and
one or more memory devices, the one or more memory devices storing computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising:
receiving acoustic signals from one or more transmitting devices associated with a real-time locating system;
selecting a set of at least two peaks from the received acoustic signals;
assigning a first set of transmitter locations to the selected set of peaks, the first set of transmitter locations specified by an acoustic model specifying a plurality of transmitter locations within an acoustic environment in which the one or more transmitting devices are located;
comparing a first model path trace associated with the first set of transmitter locations to the received acoustic signals; and
estimating a location of the computing system based at least in part on the comparison of the first model path trace to the received acoustic signals.
