| 中文摘要: |
| 为了确定地下餐饮空间内使用者主观声舒适度可接受时的声压级阈值范围，本文选取典型的封闭式地下餐饮空间作为研究对象，采用实地问卷与实测相结合的方法进行调研。结果表明：地下餐饮空间内整体环境舒适度主观评价偏低，声舒适度评价与整体环境舒适度评价具有强相关性，因此声环境是影响地下餐饮空间内整体环境舒适度的因素。在影响主观声舒适度评价的客观指标中，混响时间可不作为主要影响因素考虑;而背景噪声声压级是影响地下餐饮空间内声舒适度主观评价的重要指标。使用者声舒适度为可接受时，地下餐饮空间内背景噪声声压级阈值为70dBA—75dBA。 |

| In order to determine the sound pressure level (SPL) threshold when the acoustic comfort is acceptable,in this study, a subjective survey and objective measurements have been undertaken in typical enclosed underground dining spaces in Harbin. The results suggest that the sound environment is a factor in influencing the overall environment comfort evaluation, because they have high correlations, but the overall environment comfort evaluation is generally low. Compared with the reverberation time, the SPL of background is more important for acoustic comfort. The subjective evaluation of acoustic comfort relates negatively with the background SPL, and when the SPL is 70dBA-75dBA, acoustic comfort is acceptable. |
