Here we deal with an exact and detailed method of treating confusion phenomena in quality aspect, citing an example of confusion in band-eliminating distortion (BED). We treat these phenomena from three aspects: First, from that of timbre quality; second, from that of distortion of band-eliminating nature, and, third, from that of confusion-matrix. TIMBRE-QUALITY consists of two qualities, phonemic and vocal, which take priority over the others. In DISTORTION DIRECTION, there are two, low-cut and high-cut, both of which are necessary for our co-ordinate of observation. CONFUSION PHASE, of which there are two in confusion-matrix display, incoming and outgoing, are both at our disposal. In addition, we here present confusibility data as to phonemic and vocal confusion derived from our original experiment of 1953. In our study we emphasize three points of importance: (1) Confusion study gives the most effective means for timbre-quality study because confusion is essentially timbre phenomena in a differential sense; (2) Outgoing confusibility defined as uncertainty.of correspondence viewed from signal toward quaiity in matrix representation, and incoming confusibility defined as uncertainty of correspondence viewed from quality toward signal; (3) The intricate nature of the confusion problem can be clarified by the introduction of both incoming and outgoing confusion concepts. As the technique for introducing both confusions, we adopt, for the moment, the difference form of these two confusibilities, | Cin-Cout |, both useful for characterizing essential confusion trend for which we here give actual data in phonemic confusion and in vocal confusion. Thus from the joined inspection of both incoming and outgoing confusions. we can propose quality-formative and quality-ruinous effects of band-cutting process, which. viewed from still another angle, is the quality formative and quality-ruinous nature of band region in frequency domain.
