Buildings must ensure sound insulation appropriate to their use. This sound insulation is regulated by building regulations. In many Europe countries this is by use of the weighted apparent sound reduction index R'w or the weighted standardized level difference DnT,w.

, 2013 The “Weighted sound redution index”, Rw, described in ISO 717-1 standard, is considered a fundamental parameter for the comparison in laboratory of different building systems. This index considers a 1/3 octave band frequency range, between 100 Hz and 3150 Hz, which may not be sufficient for a satisfactory description of the behavior at low and high ...
