摘　　要：鉴于目前声品质评价采用的双耳声重放系统的存在聆听区域狭窄、重放效果因人而异和丢失立体声场信息等缺陷,文中采用了三维声场精确重放系统,对车内噪声声品质进行评价,并与基于双耳声重放系统的声品质评价结果进行比较。结果表明:与双耳声重放系统相比,基于三维声场精确重放系统的声品质主观评价与客观参量之间保持了更好的一致性,评价的准确性更高。In view of the defects of binaural sound reproduction system currently adopted for sound quality evaluation,such as the narrowness of listening bandwidth,the person-dependency of playback effects and the losses of stereo sound-field information,an accurate three-dimensional sound-field reproduction system is adopted to evaluate the sound quality of in-car noise,which is then compared with that using binaural sound reproduction system.The results show that compared with binaural sound reproduction system,the three-dimensional sound-field reproduction system can maintain a better consistency between the subjective evaluation and objective parameters of sound quality and a higher accuracy of evaluation.
