Abstract
Abstract The invention relates to a sound-damping partition, especially for the internal equipment of buildings. The partition consists essentially of a timer sub-frame (10) and two sets of planting (18, 20) on either wide side (12, 14) of the sub-frame (10) leaving a hollow space (16) filled with air and damping materials (36). To obtain improved airborne sound damping suing simple means, the invention proposes that one of the sets of planking (20) be secured to the sub-frame (10) by means of thick-walled, soft elastic beads of adhesive (32) while the other set of planting (18) is rigidly clamped to said sub-frame (10).
