1. Vibrations in Lightweight Buildings - Perception and Prediction
Abstract : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. READ MORE

2. Acoustic excitation and transmission of lightweight structures
Abstract : In order to increase our knowledge of the sound transmission and radiation processes of lightweight wall and floor structures, theoretical models are needed. Detailed models may form a valuable tool. In lightweight floor structures, impact sound insulation is perhaps the most important property to consider. READ MORE

3. Subjective assessment of vibrations in lightweight floors
Abstract : Lightweight steel floors arise a lot of attentions because of its advantages, such as cost effective, recyclable, and having a short construction period. On the other hand, low frequency vibrations induced by normal human activities get more and more complains for these types of structures. READ MORE

5. A Virtual Design Studio for Low-Frequency Sound from Walking in Lightweight Buildings
Abstract : In recent years there has been a growing interest for building lightweight multistorey woodenresidential buildings in countries like Sweden with large and renewable forests. While positive aspectsof these buildings, such as sustainability, ease of construction and lightness, motivate building more inwood, poor acoustic performance is a risk which concerns the wooden-building industry.
