1. A method comprising:
receiving multiple audio signals detected by multiple receivers, the multiple receivers positioned in a first location to receive audio transmissions from computing devices located within corresponding portions of a service area;
detecting a first audio transmission in a first subset of the audio signals, the first subset of the audio signals being received by a first subset of the receivers positioned to receive audio transmissions from computing devices located within a first portion of the service area, wherein the first subset of the multiple receivers excludes at least one of the multiple receivers;
identifying, from among multiple transmitters positioned to transmit audio transmissions to computing devices located within a service area, at least one first transmitter positioned to transmit audio transmissions to computing devices located within at least a subset of the first portion of the service area; and
transmitting a second audio transmission using the at least one first transmitter.
