G SEAL · 2024
mTRODUCTIONThis study considers the rating of the airborne sound insulation of oors which separate dwellings in terms of sound reduction index R and level difference D.Field measurements have been investigated with regard to the following:-(i)The error in an individual sound insulation rating, (ii) Ratings as the weighted standardised level difference DnT w and as the apparent sound reduction index R'w.(iii)Floors of similar commotion within the same building.(iv) Reverberation times within the receiving room.
