Summary
To ensure the acoustic performance of wood constructions, the research group at the Sustainable Building Institute at Napier University has established a series of proven solutions. The advantage of this approach is to provide designers with solutions that have been technically validated, thus allowing them to overcome the burden of proposing to the manufacturer an acoustic solution. The tools to develop this concept will involve an understanding of the propagation of impact and airborne noises in the main CLT building design typologies, validating the main solutions through laboratory testing and providing proven solutions. Many NRC (National Research Council of Canada) trials could have been avoided. Conducting tests is expensive, and it would be interesting to link the test results to the modeling results.

Summary
In order to ensure the acoustic performance of timber constructions, the research group of the Sustainable Building Institute at Napier University has established a series of proven solutions. These, called rugged construction details, are based on a series of designs that are most likely and proven for the performance they will bring into the building. The advantage of this approach is to provide designers with solutions that have been the subject of technical validations, thus allowing them to free themselves from the burden of offering the builder an acoustic solution. The tools to develop this concept will involve an understanding of the propagation of impact and airborne noise in the main building design typologies in CLT, to validate the main solutions through laboratory tests and to propose proven solutions. Many tests performed at NRC could have been avoided. Performing tests is expensive, and it would be interesting to make the link between the test results and the modeling results. Having a solution guide is great, but having a model that would predict the behavior of a design would be even better.
