  • Velcro fasteners can be closing parts 214, 216 may be arranged in order to enlarge the soundproofing wall 100 by adding further soundproofing elements and to add additional soundproofing means, for example in the form of additional soundproofing elements 202, in the areas in which adjacent soundproofing elements adjoin one another.
  • the additional soundproofing means are formed by two pocket-shaped receptacles 218, 220 which are open at the top and are provided for receiving greening 222, 224.
  • the pocket-shaped receptacles 218, 220 are connected to one another via a material web 226 and encompass the soundproofing element 2 on its lower edge essentially in a form-fitting manner, as can be seen from FIG.
  • the additional soundproofing means formed by the pocket-shaped receptacles 218, 220 extend into an area in which the lower edge of the soundproofing element 2 abuts the floor. In this way, the formation of a sound bridge is avoided in this area and the sound-absorbing effect is improved.

Abstract

L'invention concerne un élément insonorisant (2), constitué d'un premier pan (4) en matériau souple et d'un second plan (6) en matériau souple, ces pans (4, 6) étant séparé l'un de l'autre par un espace contenant au moins deux chambres (14, 16) prévues pour recevoir une matière de remplissage. Selon l'invention, les côtés des premier (4) et second pans (6) qui se font face sont reliés l'un à l'autre par des moyens de jonction. A cet effet, ces moyens de jonction comportent au moins un pan de liaison (8) en matériau souple. Ledit élément insonorisant (2) est de construction aisée et robuste ; il est aisé à manipuler et à transporter lorsqu'il n'est pas rempli de matière de remplissage. En outre, il est apte à être rempli d'une matière de haute densité telle que le sable ou un autre matériau semblable.
