It also specifies three types of construction that will meet these acoustic performance classes. Furthermore, it defines a standardized test method for measuring the acoustic performance of any type of construction, thereby allowing existing and new insulation constructions to be rated against the three classes.</p><p>ISO 15665:2003 is applicable
