摘要

评估建筑物地板系统的声学性能取决于要利用的冲击源和所使用的地板覆盖物的类型。除此之外,一个可靠的评估应该考虑听者对通过地板传播或由地板辐射的声音的判断。如果客观评分与听众的判断密切相关,则可以帮助预测房客的满意度。本研究的主要目的是比较客观和主观评价,使用两种类型的影响源和两种类型的地板覆盖物,试图确定哪些客观变量可以用来预测受试者的评价,并验证在更现实的测量中使用替代影响源的使用。根据ISO 10140:2010标准,对不同类型的地板、弹性材料和冲击声源(标准化攻丝机和校准轮胎)进行了客观评估。在对测量样品的分析中,根据所使用的声源对几个参数进行了评估。同时,记录“声音样本”,根据29名听众对两种影响源的噪音烦恼和响度感觉的判断,进行主观评价。采用了震级估计方法。结果表明,攻丝机测量值与主观评价测量值具有很好的相关性,校准后的轮胎在特定的测量设置中呈现出很好的相关性。此外,对客观变量和主观变量的线性回归分析显示了冲击噪声绝缘等级的可选单数量

Subjective evaluation of floor impact noise using the tapping machine and a non-standardized source
Assessing the acoustical performance of building floor systems relies on the impact source to be utilized and on the type of floor cover used. Besides that, a reliable assessment should consider the listeners’ judgments of the sounds transmitted through floors or radiated by them. Objective ratings measured can help to foresee tenant satisfaction provided that they are well correlated with the listeners’ judgments. The main objective of this study was to compare objective and subjective evaluations, using two types of impact sources and two types of floor covers, to try and determine which objective variables could be used to predict subject evaluation and to validate the use of an alternative impact source to be used in more realistic measurements. An objective evaluation was carried out employing impact noise insulation measurements according to ISO 10140:2010, evaluating different types of floors, resilient materials, and impact sound sources (a standardized tapping machine and a calibrated tire). In the analysis of the measured samples, several parameters were evaluated according to the sound source used. Simultaneously, "sound samples" were recorded to be used in a subjective evaluation based on the judgments of 29 listeners about the Noise Annoyance and the Loudness Sensation in response to the two impact sources. The magnitude estimation method was used. Results demonstrate that tapping machine measurements correlate very well with the subjective evaluation measurements and the calibrated tire presents well-correlated results in a specific measurement set-up. In addition, linear regression analysis of the objective and subjective variables shows alternative single number quantities for ratings of impact noise insulation
