AbstractAfter a brief view of single number quantities and psychoacoustic fundamentals used in sound insulation, reference curves provided in the new standard ISO/DIS 140-16:2003 as a method for the global assessment of airborne sound insulation improvements of lightweight wall linings are dealt with. By using a numeric simulation model the properties of airborne sound insulation improvements of wall linings resulting from that single number ratings are discussed: among then the frequency intervals of higher efficiency and the insignificance of the incident noise spectrum are noteworthy. Another important conclusion concerns the variability of global improvement as a function of the reference curve, the two curves involved in the standard project represents a certain compromise of simplicity.
