Description

In this paper, the objective assessment scale for Deep KANSEI evoked by high quality sound reproduction was investigated in the following experiments.(1) Subjective evaluation of the quality of musical sound reproduced by two different systems. One was a conventional system and the other was the Extra HI System M which could reproduce superior high quality sound by characteristics of precision wave front and planar wave.(2) Measurement of the nasal skin temperature, which is known to be an index of autonomic nervous system activity. Results showed that a greater pleasant feeling seemed to be evoked in the Extra HI System M condition compared to the condition of the conventional sound reproduction system. The long-term decrease of the nasal skin temperature, which strongly correlates to sympathetic nervous activity, showed a correlation with the subjective evaluation implying the possibility of objective assessment scale for Deep KANSEI.
