This document specifies measurement methods to characterize in the laboratory the acoustic radiation of a building element when it is directly excited by an airborne or structure-borne source. It is applicable to single-leaf and double-leaf elements (see ISO 12354‑1:2017 Annex F, F2). The measured quantity can be used as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2, to compare products, or to express a requirement.
