Summary
The objective of this work package is to provide an acoustic performance knowledge database of European timber building constructions. In a first step a methodology for structuring the planned data base will be developed. The database will be fed with existing examples from the different European timber building regions. These examples will be grouped into similar solutions and sound insulation performance. After reprocessing the data the different construction systems will be optimized in WP 2. An interface to the borad public of the database will then be developed. This user friendly and appealing front-end of the European Timber Sound Insulation Atlas (EATSI-Atlas) will provide information on various evaluation criteria, including expected future European target values.

Summary
This report comprises reslts from the work done within work package 1 in the WWN+ project "Silent Timber Build", WP 1: Prediction tools, low and high frequencies. The aim from this WP was to develop prediction tools applied for wooden constructions. Included in this is also to create necessary basis for enough accuracy for any European wood construction. It implies development of new methods but also to understand how input forces primarily from the tapping machine affects the resuts of impact sound levels. The WP also describes how models are developed, in order to provide expected accuracy and then how to further improve the models in order to optimize floor and wall assemblies. The Work Package has been closely linked to WP 2 but also WP3. Using the reults from WP 2, the prediction model results can be compared to expected values for any European construction. From that optimization of floor assemblies and refining of the model is possible.

Summary
The report includes an overview of different floor assemblies used all over Europe. They have been selected and evaluated carefully and from that the floor assemblies are divided into different groups in order to fit to limit the number of possible setups. Hence the grouping is made in a manner that will facilitate modelling of floor assemblies using the different methods as developed within this project, Silent Timber Build. It can also be used in order to recommend different floor assemblies for different buildings and usage. The software that has been used and further developed within this project is a French software adapted to wooden building floor and wall components, “SEA Wood". In addition FEM software is used in order to improve and verify the results particularly in the low frequencies, which is of particular interest for structural solutions in wood.
