Acoustics in wooden building
Lund University, Sweden
Acoustics concerns both sound and vibration, and for wooden constructions there are some important features that differ from those in concrete and other heavy constructions. The weight of a construction is an important parameter for the airborne sound insulation properties, especially for the lower frequency range, 20–200 Hz. This means that wood constructions may have poor sound insulation at the lower frequencies. Impact sound from people walking is the most common sound insulation problem for lightweight floors, especially at low frequencies. Flanking transmission is another main problem for lightweight constructions.
Low-frequency vibration and springiness can be of importance to consider especially for floors of large dimensions.
For industry, it is important to have improved knowledge concerning current requirements, as well as easily accessible data on the acoustic properties of building constructions that can be used in the early stage of building projects. It is also crucial to have reliable prediction tools in order to avoid severe and costly changes. The purpose of this mini-symposia is to gather news inputs regarding acoustics properties in wooden building.
