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