In this study, we used noise as a sound source and defined the source volume as sound pressure. We analyzed by AHP the relationship between sonority and sound pressure of the median front and surroundings, and have identified its auditory sensation. Results showed that the farther away a sound heard by the subject from the center, the worse the consistency index. The consistency index was 0.1-0.9 in such a case. That is, the consistency index when sound moved away from the median front. In addition, the consistency index was found to be 0.10-0.27 in the median front after correction was added to an up-down sound image mistaken inversely. The consistency index was 0.12-0.24 when sound sources were in the same direction and 0.16-0.63 when sources were in different directions. Correction was recognized in experiment results, but consistency worsens when sound moved away from the center. Satisfactory correction can be expected only in correction of the median front.
