The new regulations concerning building acoustics are leading to the increasing use of laminated floors. These usually offer a good solution to insulate the noises caused by impacts. However, the drum sound effect generated by these floors can be problematic. In this article, we describe a parametric study carried out on the influence that the component materials of the floor have on the sound reflected. With this objective in mind, we present a numerical 2D model using the finite element method.
