Technical Note: Comparison of the Sound Insulation of Lightweight Partitions with Different Sound Absorbing Infills
Measurements of sound reduction indices for lightweight gypsum board partitions filled with three different sound absorbing materials (rockwool, glasswool and polyurethane foam) are reported. For partitions where the gypsum panels are mounted on a common stud, with the sound absorbing infill in direct contact with both panels and for uncoupled double partitions, measurement results show that polyurethane foam, of high flow resistivity and stiffness, is less effective as an infill than either rockwool or glasswool.
