Abstract: The prefabricated floor system may produce a noticeable hollow sound when stepped on or knocked due to its structural characteristics, leading residents to question the construction quality. Based on the correlation between subjective and objective evaluation results, it is concluded that the A-weighted sound pressure level and loudness have A high correlation with annoyance degree. There is a high correlation between sharpness and roughness and hollow feeling. However, fluctuation and roughness affect the two subjective evaluation parameters of sound quality, the sense of expensive and the sense of fine. The relationship between objective evaluation parameters and subjective evaluation results is established, which has important reference significance for the subsequent design and optimization of assembled floor sound quality.

摘要： 由于住宅装配式地面体系存在架空的管线层，其敲击声存在明显的空鼓感，由此引发居住者对建筑质量的质疑。采集不同结构地面体系的敲击声样本并进行预处理，然后对样本进行声品质主客观评价，以此研究装配式地面体系敲击声品质的影响因素。将主观评价结果与客观评价结果进行相关性对比分析得出：A计权声压级和响度与烦恼度有较高的相关性；尖锐度和粗糙度与空鼓感有较高的相关性；波动度和粗糙度则与昂贵感和精致感相对应。研究结果建立了客观评价参数与主观评价结果之间的联系，对后续装配式地面体系声品质优化有重要指导意义。
