Measurement of sound insulation in buildings and of building elements using sound intensity - Field measurements shop-only It explains why some principlesWhat is ISO 15186 2 Field measurements of sound insulation in buildings about? ISO 15186 2 is the second part of the multiple series document that specifies a sound intensity method to determine the in situ sound insulation of walls, floors, doors, windows and small building elements. ISO 15186 2 is intended for measurements that have to be made in the presence of flanking transmission. ISO 15186 2 can be used to provide sound power data for
