Soundproofing element; has two spaced flexible sheets joined by flexible connection sheet, which is alternately connected to each sheet in zigzag or meander pattern to form chambers for filler medium

摘要

The element (2) has two spaced sheets of flexible material, which are joined by a connection sheet of flexible material. The connection sheet extends along the length or height of the sheets and is alternately connected to each sheet, in a zigzag or meander pattern at strip-shaped vertical connection points (12). The sheets form at least two separated chambers that can be closed, to hold a filler medium. An Independent claim is included for a soundproofing wall incorporating the element.
