TUAS 2023 Floor Sound Insulation Rev1

Turku University of Applied Sciences (Turku, Finland) was funded in 2020-2023 by the Ministry of the Environment (Finland) for a research project to investigate various aspects related to the impact sound insulation of wooden intermediate floors that are used in multistorey apartment buildings. The research required reliable and reproducible data of impact sound insulation for a broad range of floor constructions. Therefore, large number of floors was built and measured in the building acoustics laboratory of Turku University of Applied Sciences. The data was laborious and expensive to collect because of extensive physical construction work. Therefore, the outcoming data collection is remarkable and unique.
Four different load-bearing slabs were inspected (cross-laminated timber slab 140 mm, cross-laminated timber slab 260 mm, open box timber slab 370 mm, steel-reinforced concrete slab 160 mm). The load-bearing slabs were not tested barely since bare slab do not fulfil any sound insulation requirements. Therefore, the tested floors involved at least a floor covering. In addition, the floors involved either floating floor (several alternatives), or a suspended ceiling (several alternatives) or both.
The data can serve the development of sound insulation prediction models, experimental analysis of sound insulation, product development of floor construction, and education.
The data contains well-documented impact and airborne sound insulation measurement results of 30 wooden floors and 8 concrete floors. The data elucidates, how different floor toppings and suspended ceilings affect the sound insulation. The specialties of these data are: the data were obtained in the same laboratory within a limited period involving the same professional installation team; the measurements were conducted in a broad frequency range (20 to 5000 Hz); detailed structure drawings for each floor construction are given.

This version 2 does not contain changes to Version 1 related to the main data (sound insulation and construction drawings). This version 2 contains one more file which contains photographs about the constructions.

芬兰图尔坎应用科学大学（Turku University of Applied Sciences）于2020年至2023年获芬兰环境部资助，开展一项研究项目，旨在探究多层公寓建筑中使用的木质中间楼板的撞击声隔声（impact sound insulation）相关的各类问题。该研究需要针对广泛的楼板构造获取可靠且可复现的撞击声隔声数据。为此，研究团队在图尔坎应用科学大学的建筑声学实验室中搭建并测试了大量楼板。由于需要开展大量实体建造工作，该数据集的采集工作耗时耗力且成本不菲，因此本次采集得到的数据集极具价值且独一无二。

本次研究共测试了四种不同的承重楼板：140mm厚交叉层压木板（cross-laminated timber slab）、260mm厚交叉层压木板、370mm厚空心箱型木板（open box timber slab）以及160mm厚钢筋混凝土板（steel-reinforced concrete slab）。由于裸楼板无法满足任何隔声要求，因此并未仅对裸楼板进行测试。本次测试的楼板均至少配备了楼面面层，此外还可能加装了浮筑楼板（floating floor，含多种方案）、吊顶（suspended ceiling，含多种方案），或同时加装两者。

该数据集可用于隔声预测模型的开发、隔声实验分析、楼板构造产品研发以及教学工作。

数据集包含30个木质楼板与8个混凝土楼板的记录完备的撞击声及空气声隔声（airborne sound insulation）测量结果，清晰阐明了不同楼面面层与吊顶对隔声性能的影响。该数据集的特色之处在于：所有数据均于同一实验室、在有限周期内由同一专业安装团队完成采集；测试覆盖了20Hz至5000Hz的宽频率范围；并提供了每种楼板构造的详细结构图纸。

本版本2未对版本1的核心数据（隔声及结构图纸）进行任何修改，仅新增了一个包含楼板构造相关照片的文件。
