Optimization of the acoustic performances of lightweight sandwich roof elements KU Leuven
Lightweight roof elements are commonly used in buildings because of the ease and speed of installing and the potential for very high and reliable thermal insulation. The sound insulation of the sandwich panels however may be too low. In fact, the combination of low mass and high stiffness typically results in a lower sound transmission loss over a large frequency band. But regularly the presence of higher outdoor levels is reflected in stricter ...
