Description
Engineered wood constructions and timber buildings are rapidly developing, while the numerical techniques
usable for their sound insulation properties are various and often still under development. This research constitutes
a first step towards the reliability determination of building acoustics simulations on timber-based elements.
A small scale round robin involving five research laboratories is presented. The results obtained show
significant deviations depending on the chosen numerical method and indicate how laboratory measurements
could not be approximate with a good accuracy. Finally, a sensitivity analysis is presented and challenges as well
as requirements for reliable timber structures acoustic predictions are discussed.
