TUAS 2023 Floor Sound Insulation

TTurku 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 DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
