Evaluation of Influencing Factors on Sound Quality of Prefabricated Ground Systems of Residential Buildings
2026, 46(1):
241-246.
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.
