A retrofit wall system (600) and a method for retrofitting a preexisting wall to increase sound attenuation characteristics includes resiliently mounting construction members (608) onto a preexisting wall surface and mounting a new wall surface (for example, drywall) thereover. It is desirable to provide insulation (612) (thermal and/or acoustic) between the construction members to further increase sound attenuation. The construction members may be conventional members (606) (for example, a 2"x4" (5.08 cm x 10.16 cm)) resiliently mounted using a resilient channel or web (610), or they may simply be resilient members directly fastened to the new and old wall surfaces, respectively.

Un système (600) de rattrapage de mur et un procédé de rattrapage d'un mur préexistant pour augmenter les caractéristiques d'insonorisation consiste à monter de manière souple des éléments de construction (608) sur une surface murale préexistante et à monter une nouvelle surface murale (par exemple une cloison sèche sur celle-ci). Il est souhaitable de prévoir l'isolation (612) (thermique ou acoustique) entre les éléments de construction afin d'améliorer davantage l'insonorisation. Les éléments de construction peuvent être des éléments classiques (606) (par exemple, 2'' x 4'' (5,08 cm x 10,16 cm)) montés de façon souple à l'aide d'un canal ou d'une âme souple (610), ou ils peuvent être simplement des éléments souples fixés directement sur les surfaces murales nouvelles et anciennes respectivement.
