The basic factors of stereophonic sound which contribute to improve the higher qualities were analysed by means of factor analysis as follows. (1)The higher qualities of stereo, for example vividness, clearness, definition, richness etc. were scaled in previous reports. (2)Coefficients of correlation between these scales calculated by a special method. (3)These coefficients represented in matrix. (4)This matrix analysed by factor analysis. (5)As a result, we can see the fact that the basic factor of stereophonic sound is the reproduction of the character of space. (6)Furthermore, it separated by two factors, the first the character of orientation or selectivity, and second the character of inhibition of offensive reverberation. These two factors mean commonly our ordinary hearing experience in the hearing space. And therefore, the cause of superior qualities in stereophonic sound understood as follows; the sound of stereo give us the natural hearing, in other words, it means the matching in a true meaning to our hearing.
