주행시 차량 흡기소음의 음질지수 개발에 관한 연구

This paper is represented study on the development of the sound quality for the evaluation of a vehicle intake noise using a correlation analysis of the objective measurement and the subjective evaluation data. At first, an intake orifice noise was measured at the wide-open throttle sweep condition. And then, acoustic transfer function between the intake orifice noise and the interior noise at the steady state condition was measured. Simultaneously, subjective evaluation was carried out with a 10-scale score by 8 special engineers. Next, the correlation analysis between the psychoacoustic parameters derived from the measured data and the subjective evaluation was performed. The most critical factor was determined and the corresponding sound quality index for the intake noise was obtained from the multiple factor regression analysis method. At last, the effectiveness of the proposed index was validated.
