1. An unmanned aircraft, comprising:
a microphone including a plurality of elements;
a rotor blade used for flight; and
a processor that processes signals output from target elements included in the plurality of elements,
wherein the processor:
obtains an aircraft state of the unmanned aircraft;
changes the target elements that output the signals to be processed by the processor to select at least one target element that outputs a signal to be processed by the processor from among the plurality of elements, in accordance with the aircraft state;
increases a current number of the target elements in changing the target elements; and
before the changing of the target elements, the target elements include a first element located in a specific direction from the microphone, and
wherein the aircraft state is a current number of rotations of the rotor blade per unit time.
