Abstract

Example techniques relate to playback based on acoustic signals in a system including a first playback device and a second playback device. A first playback device may detect a first acoustic signal. The first playback device sends, to a network device, data corresponding to the detected first acoustic signal. The network device may generate one or more instructions based on the sent data corresponding to the detected first acoustic signal and send data representing such instructions to the first playback device. Based on the instructions, the first playback device plays back audio content. Further, the second playback device may stop playing back audio content based on further instructions.
