| Outline of Final Research Achievements |
We developed an evaluation method of approaching sign signal of EV/HEV. We developed sound evaluation system using four of B-format microphones. We developed evaluation method of sound localization and presented in IEIEC. For an example, interference of tone signal to the limited band noise signal, is constant 7dB regardless frequency of the first signal is within the critical band of second signal. Which is new and valuable finding in this area.
