The optimized individual sound environment is necessary to more than one people in the Smart Sound Space having the ability to support the activities of the people. In this research, multi-zone sound field control using multi-speaker in interior space of the car is researched. For the purpose of the evaluation for the multi-zone, the physiological reaction is evaluated using oxy-Hb by the optical topography (NIRS) and LF/HF based on RRJ of the electrocardiogram in order to achieve the separation of the space based on objective assessment. The effect for the SPL change of the music and car-navigation voice under the cruise noise is observed by the 12 subjects.
