Abstract
Systems and methods for detecting and acknowledging audio transmissions containing data. In one embodiment, a method is presented that includes receiving multiple audio signals that are detected by multiple receivers from within a service area. A first audio transmission may be detected in a first subset of the audio signal that are received by a first subset of the receivers. The first subset of the receivers may be positioned to receive audio transmissions from computing devices located within a first portion of the service area. At least one transmitter may be identified that is positioned to transmit audio transmissions to computing devices located within at least a subset of the first portion of the service area. A second audio transmission may be transmitted using the at least one first transmitter.
