Acoustics. Measurement of sound insulation in buildings and of building elements using sound intensity - Laboratory measurements at low frequencies not-eligible List of symbols and abbreviations1 Scope 1. 1 General This part of ISO 15186 specifies a sound intensity method to determine the sound reduction index and the element normalized level difference of building elements at low frequencies. This method has significantly better reproducibility in a typical test facility than those of ISO 1403, ISO 14010 and ISO 151861. The results are more independent of the room dimensions of the laboratory and closer to values that would be measured
