Abstract
A method and an apparatus for controlling a multi-microphone noise-canceling sound pickup range of a terminal, and belongs to the field of terminal technologies, where the method includes transmitting a first non-voice signal, receiving a second non-voice signal that is obtained after the first non-voice signal is reflected by a reflecting object, determining, according to the first non-voice signal and the second non-voice signal, whether a posture with which a user holds a terminal during a call is a normal posture, and adjusting a multi-microphone noise-canceling sound pickup range of the terminal when the posture with which the user holds the terminal during the call is not a normal posture. Hence, accuracy of adjusting a multi-microphone noise-canceling sound pickup range of a terminal can be improved. The apparatus includes a transmission module, a receiving module, a first determining module, and an adjustment module.
