Abstract Impact noise is increasingly becoming an important issue both in terms of technologies for its reduction and in terms of its perception inside buildings. In fact, a high level of noise clearly affects indoor comfort and liveability of confined spaces. For this reason, this study focuses on the influence which the static load over time impacts on the resilient material of a floating floor and on its final performance. Five different types of resilient materials have been tested for five years and the results are analysed in terms of material type, surface contact and thickness variation, dynamic stiffness measured on 8 different time steps and its application on 6 different bare floors. Obtained values are therefore studied in terms of perceived comfort and compliance with 31 European countries regulations limits. Results clearly show that time has a paramount influence on all types of resilient materials (with the exception of one) in all configurations and that complete floor selection, in time, can greatly change perceived indoor living comfort and compliance with the limits imposed by laws.

时间对浮动地板的影响综合分析：对声学性能和居住者舒适度的影响

摘要 撞击噪声在降低噪声的技术和建筑物内部感知方面正日益成为一个重要问题。事实上，高水平的噪音显然会影响密闭空间的室内舒适度和宜居性。因此，本研究侧重于静载荷随时间推移对浮动地板弹性材料及其最终性能的影响。五年来对五种不同类型的弹性材料进行了测试，并从材料类型、表面接触和厚度变化、在 8 个不同时间步长上测量的动态刚度及其在 6 个不同裸地板上的应用等方面对结果进行了分析。因此，根据感知舒适度和符合 31 个欧洲国家/地区的法规限制来研究获得的值。
