Influence of constructive options on the vibro-acoustic behavior of a wooden lightweight structure

This paper aims to present the influence of several constructive options on the vibro-acoustic behavior of a wooden lightweight structure. The experiemental protocol, which was optimised and described in an preceeding paper [1], allows us to quantify the influence of these constructive options in terms of acoustic level and isolation, eigenfrequencies and vibration mode shapes of the different parts of the structure. The results of this work are coherent and confirmed that the experimental test protocol is functional and repeatable.
