Summary
AcoustiTECH is a North American leader in acoustic solitions and has quickly become the reference standard in the industry. For 25 years, AcoustiTECH has teamed uo with Architects, builders, general contractors, acoustic consultants and other stakeholders to help them achieve their vision by providing proven acoustical solutions and expertise. AcoustiTECH looks at the specific requirements of each individual project, evaluates the requirements, determines the needs and provides personalized solutions. AcoustiTECH's approach is unique, efficient and reliable. We possess our own acoustic laboratory that we use for our research and development in order to recommend the best acoustic solutions by type of structure. Thousands of tests have been performed inclusing over 300 on heavy timber assemblies. The principal objective of creating this document is for the professionals to compare and choose from 25 assemblies the ones that suit their needs the best. The most interesting and popular assemblies have been selected and compared side by side in the same environment, built and tested by the same professional unisg the same flooring materials. It is important to note that the quality of construction can affect the performance. Indeed, construction standards and assemblies recommendations must be followed in order to reach the seeking performance.

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.
