Title: TEST EQUIPMENT MAKER'S COOPORATIVE APPROACH TO THE MEASUREMENT NEXT GENERATION AUTOMOTIVES: COMPARISON OF NOISE AND VIBRATION CHARACTERISTICS BETWEEN ICE VEHICLE AND EV
text: The car's ride of electric vehicle (EV) is quite different from that of internal combustion engine(ICE)vehicle. Nonetheless, only limited discussion has held so far. We have carried out noise and vibration measurements using EV in order to compare to ICE vehicle. We have found that sound quality index in addition to sound pressure level are useful to evaluate distinguished sound of EV. Also, the characteristics of sound field in cabin are found to be quite different each other.
