適用范圍：This part of ISO 15186 specifies a sound intensity method to determine the sound reduction index and the elementnormalizedlevel difference of building elements at low frequencies. This method has significantly betterreproducibility in a typical test facility than those of ISO 140-3, ISO 140-10 and ISO 15186-1. The results are moreindependent of the room dimensions of the laboratory and closer to values that would be measured between roomsof volume greater than 300 m
