Omfang

This part of ISO 140 gives a laboratory method of measuring airborne Sound insulation under diffuse field conditions of such small building elements as are defined below. lt is intended that the results obtained will be used to develop building elements with appropriate acoustical properties, to classify such elements according to their Sound insulation properties and to estimate their influence on the Sound insulation of partition constructions in buildings. This part of ISO 140 applies to building elements, excluding windows and doors, with an area of less than 1 m* and which occur in a certain number of discrete sizes with weil-defined lateral dimensions and which transmit Sound between two adjacent rooms or between one room and the open air inde- pendently of the adjoining building elements. Some examples of equipment covered by this part of ISO 140 are transfer air devices airing Panels (Ventilators) outdoor air intakes electrical raceways (cable ducts) transit sealing Systems The method given is not primarily intended for components that constitute part of an integrated unit for which the associated Sound transmission might depend on an interplay of components.
