A beamforming method and apparatus for acquiring a sound signal in an electronic device includes selecting at least one object for beamforming to acquire a sound, measuring a first distance between the at least one object selected and a sensor for distance measurement, calculating a second distance between the at least one object and a plurality of microphones based on the first distance, and determining a weight for sound beamforming using at least one of time delay and phase delay corresponding to the second distance between the object and the microphone.
