適用范圍：This part of ISO 15186 specifies a sound intensity method to determine the in-situ sound insulation of walls, floors, doors, windows and small building elements. It is intended for measurements that have to be made in the presence of flanking transmission. It can be used to provide sound power data for diagnostic analysis of flanking transmission or to measure flanking sound insulation parameters.This part of ISO 15186 can be used by laboratories that could not satisfy the requirements of ISO 15186-1, which deals with laboratory measurements with no or little flanking transmission. ISO 15186-3 deals with measurements under laboratory conditions, at low frequencies.This part of ISO 15186 also describes the effect of flanking transmission on measurements made using thespecified method, and how intensity measurements can be used? to compare the in-situ sound insulation of a building element with laboratory measurements whereflanking has been suppressed (i.e. ISO 140-3),? to rank the partial contributions for building elements, and? to measure the flanking sound reduction index for one or more transmission paths (for validation ofprediction models such as those given in EN 12354-1).This method gives values for airborne sound insulation, which are frequency dependent. They can be converted into a single number, characterizing the acoustic performance, by application of ISO 717-1.
