Acoustics - Measurement of sound insulation in buildings and of building elements Part 4: Field measurements of airborne sound insulation between rooms
出版：International Organization for Standardization
專家解讀視頻
Gives field methods that are used to measure the airborne sound insulation properties of interior walls, floors and doors between two rooms under diffuse sound field conditions in both rooms, and to determine the protection afforded to the occupants of the building. These methods give values for airborne sound insulation which are dependent on frequency. The obtained results can be used for comparing sound insulation between rooms and actual sound insulation with specified needs.
