PPROBLEM TO BE SOLVED: To play back a target sound of a high S/N ratio by eliminating noise from the target sound collected by one microphone normally. PSOLUTION: The sound source separation learning apparatus uses signals collected by two microphones in advance to acquire first learning data constituted of weight values by bands for noise elimination that becomes a model case, and a class of an acoustic feature amount with which a weight value by bands most approximate to the first learning data, as second learning data. The sound source separation apparatus calculates a weight value by bands for noise elimination using the acoustic feature amount of the class designated by the second learning data for a signal collected by a single microphone, multiplies each of band dividing signals dividing the signal collected by the single microphone into bands by the weight value by bands, and eliminates a noise component.
