Acoustics — Measurement of sound insulation in buildings and of building elements — Part 10: Laboratory measurement of airborne sound insulation of small building elements
ADOPTED_FROM:ISO 140-10:1991
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.
