Part 2: Measurement-Based Investigation of the Sound Radiation of Suspended Ceilings T2 - Deutsche Gesellschaft für Akustik e.V. (ed.), Fortschritte der Akustik - DAGA N2 - In this contribution a method for the prediction of the radiated sound out of the velocity field of a vibrating ceiling is presented. The numerical method was validated via measurements on a real structure using a pp-probe. It is based on Integral Transform techniques and can be applied in the postprocessing of a FEM simulation (harmonic analysis) [1]. The method was verified by measurements on the real structure and can be used for parametrical studies. Rounding off the Parts 1 and 2 of this publication nomograms, based on dimensionless parameters, can be developed to predict the sound radiation of light weight slabs. Hereby different sets of geometry as well as different configurations of ceilings can be studied in order to describe the acoustical and dynamical behaviour of wooden ceilings.
