Abstract
Various aspects include approaches for controlling acoustic beams. In some particular aspects, a system includes: a microphone array; and a control system coupled with the microphone array, the control system programmed to control the microphone array by: processing a signal from a beacon device to identify a physical location of the beacon device relative to the microphone array; and focusing the microphone array in a direction based upon the physical location of the beacon device prior to receiving an audio input at the microphone array.
