Beschreibung
Zusammenfassung:	For the sound insulation of rooms, use is made of acoustic panels which can be assembled to form ceilings and, on the one hand, are intended to have a high degree of sound absorption over the entire audible frequency range or specific selected bands, but, on the other hand, have to be easily machinable and have to be able to be provided with a corresponding colour or textured coating. Suitable for this purpose are sandwich-structure acoustic panels, in the case of which an easily machinable carrier panel, preferably a particle board, is provided with a covering layer which is directed towards the room wall or room ceiling and consists of a thin nonwoven or of a perforated sheet, the carrier panel being equipped with through-passage bores since it does not itself have any capacity for sound absorption.
