A microphone array system includes a camera that images a picture for a target place, and a microphone array that picks up sound. A sound source position is calculated based on the picked up sound. An image is displayed on a display, the image including an imaged target place picture and a sound source position mark indicative of the sound source position. An instruction of a specified spot is received in the target place picture displayed on the display. Sound directivity is formed in a direction from the microphone array toward the specified spot based on the picked up sound, and sound data is generated by emphasizing sound in the direction in which the sound directivity is formed. The generated sound data is output to the speaker to reproduce the sound data.

Detecting sound sources in a physical space-of-interest is challenging due to strong ego-noise from micro aerial vehicles (MAVs) propeller units, which is both wideband and non-stationary. The present subject matter discloses a system and method for acoustic source localization with aerial drones. In an embodiment, a wideband acoustic signal is received from an aerial drone. Further, the wideband acoustic signal is splitted into multiple narrow sub-bands having cells. Moreover, from a measurement position corresponding to each of the multiple narrow sub-bands, power in each of the cells is measured by forming a beam to each of the cells. In addition, intra-band and inter measurement fusion of the measured power at each of the cells is performed. Also, geo-location of an acoustic source corresponding to the wideband acoustic signal is identified upon performing intra-band and inter measurement fusion of the measured power.
