Abstrakt

Noise propagation in lightweight building structures is an issue that needs attention in the current building trend. In this paper, a finite-element model is utilized for the analysis of flanking noise transmission in a lightweight panel structure consisting of two plates with internal ribs using various joints between the studs and the plates. Four different coupling configurations are considered: 1) all structural contact points are completely tied; 2) only nodes on the centre lines of the structure are tied; 3) a narrow strip of 5 mm, 10 mm or 20 mm tied elements connect the frame to the plates; 4) evenly spaces discrete elements are tied. The computations are carried out in the frequency domain with diffuse-field excitation of the source panel in the frequency range below 500 Hz.
