Abstract

Zur Vereinfachung der Herstellung und Montage und zur Verbesserung der Breitbandigkeit des Absorptionsspektrums sind schallabsorbierende Bauteile für Wände, Böden und Decken mit mindestens einer gelochten oder perforierten Platte (1) bzw. Schicht einer Dicke von weniger als 50 mm versehen, welche kleine Durchbrechungen (2) mit einem mittleren Durchmesser D bzw. einer mittleren Breite b zwischen 0,001 und 2 mm und ein Lochflächenverhältnis LV zwischen 0,1 und 20% bei einer Dicke L der Platte (1) zwischen 0,01 und 50 mm aufweisen.

Figure 00000001
In order to simplify the manufacture and assembly and to improve the broad spectrum of the absorption spectrum, sound-absorbing components for walls, floors and ceilings are provided with at least one perforated or perforated plate (1) or layer with a thickness of less than 50 mm, which has small openings (2) have an average diameter D or an average width b between 0.001 and 2 mm and a hole area ratio LV between 0.1 and 20% with a thickness L of the plate (1) between 0.01 and 50 mm.
