| Summary: | This thesis presents a concept for improving a wood roof from an acoustical point of view. The normative related to noise is going to demand higher levels for airborne insulation and also for noise impacts so it is necessary to improve the acoustical part of these constructive elements. A deep study of acoustics and also of roofs: parts, functions, manufacturing… and materials to make them has helped to solve the problem. The knowledge of how sound is produced, propagated and how it can be reduced has given a solution to the problem (concepts creation and choice). The result is a prefabricated wood sandwich panel with a rock wool and rubber core which is enough justified to perform all normative related to noise and sound as well as other functions like supporting, thermal purposes etc. All the parts have been explained adequately and also it has been suggested how the module can be constructed as well as the assembly in the final structure.
