Abstract

Ein schallabsorbierendes Element (1) zur Aufbringung an einer Decke oder Wand (7), vorzugsweise an der Innenseite einer Gebäudeaußenwand, ist gekennzeichnet durch einen Aufbau aus einer Unterschicht (2) mit Zellulose als Hauptbestandteil und einer mit der Unterschicht (2) flächig verbundenen Oberschicht (3), die ein höheres spezifisches Gewicht als die Unterschicht aufweist. Das schallabsorbierende Element weist in einem breiten Frequenzbereich hervorragende akustische Absorptionseigenschaften auf, kann sich über die gesamte Fläche von Wänden oder Decken von Räumen erstrecken, ohne in architektonischer Hinsicht störend zu sein und wirkt auch als Dampfbremse im Innenbereich.

Figure imgaf001
A sound-absorbing element (1) for application to a ceiling or wall (7), preferably on the inside of a building exterior wall, is characterized by a construction of a sub-layer (2) with cellulose as the main constituent and a surface layer connected in a planar manner to the sub-layer (2) (3) which has a higher specific gravity than the lower layer. The sound absorbing member has excellent acoustic absorption properties in a wide frequency range, can extend over the entire surface of walls or ceilings of rooms without being architecturally troublesome, and also acts as a vapor barrier in the interior.
