This part of ISO 15186 specifies a sound intensity method to determine the sound reduction index and the elementnormalized level difference of building elements at low frequencies. This method has significantly better reproducibility in a typical test facility than those of ISO 140-3, ISO 140-10 and ISO 15186-1. The results are more independent of the room dimensions of the laboratory and closer to values that would be measured between rooms of volume greater than 300 m3. This part of ISO 15186 is applicable in the frequency range to but is mainly intended for the frequency range 50 Hz to 160 Hz. For elements faced with thick, porous absorbers, the recommended frequency range is 50 Hz to 80 Hz.
