This paper reports and discusses the results of on-site measurements carried out on a lightweight multi-layered gypsum partition in a full-scale experimental ZEB building. The wall configuration under study was first characterized in laboratory and then on-site, in a situation that presented many issues related to flanking transmissions. In order to minimize the flanking transmissions, modifications were made to the lateral elements, step by step. At each step, the measurement of the sound transmission loss was repeated until the highest possible value was reached. The on-site acoustic insulation performance was also estimated by applying a calculation model and compared with the measurement result. The internal partition was finally classified according to the main procedures in force in Italy.
