The qualities of stereophonic sound reproduced by binaural earphones were scaled by means of the method of paired comparison. The concepts of the quality treated here were composed of twelve different characters; vividness, richness, pleasingness, powerfulness, clearess, loudness, presence, feeling of distance, separation of signal from noise, feeling of moving sound image, and feeling of offensive reverberation. The method of experiment and method of scaling were as same as described in Report I. In this report, following problems were also treated; the first was the method of extraction of quality concepts, the second was meaning of unit of psychological scale. As the result of this experiment, a psychological scale in each qualities was obtained, and it was shown quantitatively by using these scales that the stereophonic system had character of high fidelity. As a consequence of these Reports I and II, a new method for rating higher qualities was established.
