    초록 The driver‘s perception on the vehicle noise is affected largely by psychoacoustic characteristic of the noise as well as the SPL. In particular, the HVAC sound among the vehicle interior noise has been reflected sensitively in the side of psychology. In previous study, we have developed to verify identification of source for the vehicle HVAC system through multiple- dimensional spectral analysis. Also we carried out objective assessments and subjective assessments. In this study, the linear regression models were obtained for the subjective evaluation and the sound quality metrics. The regression procedure also allows you to produce diagnostic statistics to evaluate the regression estimates including appropriation and accuracy. To enhance sound quality, we applied ANC which is effective in the low-frequency bandwidth. As a result of ANC simulation application, sound quality is improved by more quiet, powerful, expensive, smooth.
