| Abstract | The determination of the total and the resonant components of the radiation efficiency have been shown to be necessary for the accurate prediction of the resonant sound reduction index for the calculation of the flanking sound reduction according to a proposed revision of the ISO 15712 series. However, the total and the resonant radiation efficiency of lightweight building elements can be difficult to determine experimentally and there is often confusion about what has actually been measured. In this paper, measurements in the laboratory of the components of the radiation efficiency are presented for different lightweight walls. The measurements were made using both sound intensity and sound pressure to determine the sound power radiated from the walls. Different methods of excitation are compared. A standard for the measurement of the components of the radiation efficiency of lightweight walls is necessary. |
