English abstract:
Different measurement methods of radiation efficiency are investigated. The first method uses an intensity probe and a laser vibrometer. The second method is based on the measurement of the sound pressure level in a diffuse sound field. The third method (Discrete Calculation Method - DCM) applies the Rayleigh integral method to calculate the radiated sound power into the semi-infinite space by measuring surface velocity with a laser scanning Doppler vibrometer. In a second step, a finite-element-model of the investigated lightweight building construction is presented. The results of these simulations are compared to the results of the investigated measurement methods.
