Abstract: Provided are a sound source separation apparatus and a sound source separation method. The sound source separation apparatus includes a plurality of directional vibrators configured such that one or more of the plurality of directional vibrators react to a sound based on a direction of the sound. The sound source separation apparatus is configured to determine directions of a first sound source and a second sound source that are different from each other, based on strengths of output signals of the plurality of directional vibrators, and select a first directional vibrator and a second directional vibrator that are different from each other from among the plurality of directional vibrators to separately obtain a sound coming from the first sound source and a sound coming from the second sound source.
