This paper proposes an estimation method for the number of source signals under a two-sensor condition. A joint distribution of observed mixture signals by microphones has the same number of lines as the source signals. Therefore, we propose a number estimation method using Hough transform. The method can estimate using only observed mixture signals. Additionally, we propose a blind source separation method based on the estimated number of the source signals. The proposed methods have been verified by several simulations.
