Acoustic solutions for wooden intermediate floors
In Switzerland multi-storey timber construction has been very successful in recent years. This is primarily due to the 2005 amended fire safety regulations. This development brought with it new challenges with regard to sound mitigation. Apart from requirements governed by national standards, there are requirements driven by occupants. These are based on subjective human perception and can lead to complaints about low-frequency sound even if the values specified in the standard are met. Research was therefore carried out on the subjective assessment with in-situ measurements, a broad survey and auditory tests. Additionally common details and their robustness where evaluated and within 4 case studies examined. The results of the research project in short are: - The frequency range for sound insulation needs to be considered from 50 Hz - Building elements show a wide range of construction principles and acoustic properties. A structured online catalogue with robust details was developed - With good floor build-ups, the flanking transmission is of minor importance - One main reasons for the small sound insulation properties of timber constructions in the low frequency range is the low mass - The quality of elements/buildings must be guaranteed. Timber constructions can be controlled significantly in industrialised building systems
