ISO 15186 3 is the third part of the multiple series that 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 140 3, ISO 140 10, and ISO 15186 1.
