Method and system for acoustically triggering electronic coupon retrieval

A method and system for acoustically triggering wireless network communication and reporting. A portable device monitors external audio waveforms comprising broadcast media, to detect at least one predefined acoustic frequency embedded in the waveforms. In response to the detection, the portable device takes an action with respect to a wireless network, preferably relating to the at least one detected acoustic frequency. The invention can be used advantageously to monitor broadcast media consumption.
