This paper presents an investigation of prediction metrics for structure-borne noise in timber buildings, based on the vibration response of the structure. The purpose of the study is to derive a robust measure for predicting structure-borne noise in

The paper demonstrates improved structural low-frequency vibroacoustic performance of crosslaminated timber (CLT) floor panels by informed selection of the wood material. The use of wood species and strength classes that are not traditionally assigne

The use of wood as construction material in multi-story buildings increased in Europe during the last decades. Wood buildings are more sensitive to dynamic loading compared to conventional concrete buildings, especially in terms of vibroacoustic comf

The main challenge in predicting structure-borne sound in wood buildings is to accurately model the vibration transmission between the source and the receiving room. Large variations in model parameters make it difficult to predict absolute vibration

Dynamic substructuring is often employed to reduce the size of numerical models for structural dynamic analysis. In this paper, we discuss how elastomeric vibration isolators can be modelled within the framework of dynamic substructuring in order to

To predict the vibroacoustic performance of complex thin-walled structures, an analysis using a finite element model considering structure–acoustic interaction is often required. The acoustic response of such models can be time-consuming to compute

Determining the dynamic behaviour of lightweight buildings by means of finite element analyses requires models representing the geometry involved in great detail, resulting in systems having many millions of degrees of freedom. It is, therefore, impo

Regulations regarding impact and airborne sound insulation for lightweight timber constructions have become increasingly stringent due in particular to complaints by inhabitants. Accordingly, some building techniques frequently use elastomers at junc

Lightweight buildings are sensitive to low-frequency vibrations, making it difficult to construct them in such a way that noise and disturbing vibrations are kept at an acceptable level. In the design of vibration reduction measures, it is desirable

In order to reduce the vibration transmission in multi-storey wood buildings, it is common to insert viscoelastic elastomer materials between parts of the buildings. The studies presented here investigate to which extent different design choices for
