Subjective and objective acoustic performance ranking of heavy and light weight walls

The results were analysed and used to rank the walls from best to worst according to the perceived loudness of the sound samples. It has been shown that lightweight walls are better ranked than heavy walls, not only when compared to those with the same RA,50-5000, but in some cases also when the RA,50-5000 of the heavy wall is higher than the RA,50-5000 of the lightweight one. Furthermore, the ranking obtained from the listening test results matches very well with the ranking made according to Rw + C ≈ RA,100-3150.
