Es befinden sich Platten der vorbeschriebenen Art im Handel, die eine verhältnismäßig gute Geräuschdämpfung bei 10U0 bis 2500 Hz aufweisen. Der Absorptionskoeffizient nimmt jedocn bei ainer Frequenz von mehr als 2500 Hz stark ab, so daß die bisiier bekannten Platten bei Frequenzen über 25OU iiz die gestellten Anforderungen nicht erfüllen.The human ear is not the same for all G-noises Einpfindlion.

There are plates of the type described above in the trade, which have a relatively good noise attenuation at 10U0 to 2500 Hz. The absorption coefficient however, increases sharply at a frequency of more than 2500 Hz from, so that the bisiier known plates at frequencies above 25OU iiz do not meet the requirements.

Das Verfahren nacn der Erfindung besteht darin, daß Mineralwolle und/oder Glaswolle zu Blatten von einem Gewicht von 75 bis 9D lcg/nr und einer Dicke von mindestens 15mm zusammengepreßt und diese geschliffen und ein- oder beidseitig mit einer Glasfaserhaut versehen werden. Die beispielsweise ausr. von einem organischen Bindemittel zusammengehaltenen Glasfasern bestehende Glasfaserhaut wird vorteilhaft mit einem Lack überzogen, was zweckmäßig unter Anwendung eines Siebdruckverfahrens geschieht. Das Siebdlruckverfahren zum Aufbringen des lacks auf der bereits mit einer Glasfaserhaut versehenen Mineralwoll- oder Glas= wollplatte hat gegenüber einem Spritzverfahren den Vorteil, daß mit ihm eine gleichmäßigere Verteilung des Lacks über der Platte entsprechend einem konstanten Muster erzielt wird.see 500 and 7000 Hz on a constant honing value held. The method according to the invention consists in that mineral wool and / or glass wool to sheets of a weight of 75 to 9D lcg / nr and a thickness of at least 15mm pressed together and sanded and provided with a fiberglass skin on one or both sides. the For example, glass fiber skin consisting of glass fibers held together by an organic binder is advantageously coated with a varnish, which is expediently done using a screen printing process. That Screen printing process for applying the paint to the mineral wool or glass that is already covered with a fiberglass skin = Wollplatte has the advantage over a spraying process that it allows a more even distribution of the paint over of the plate is achieved according to a constant pattern.

Bei der Herstellung einer geräuschdämpfenden Platte nach der Erfindung wird vorzugsweise eine mit Lack versehene Glasfaserhaut mit einer Oberfläche, die etwas größer ist als die der zu biaeckenden Platte aufgebracht, so daß die Giasfaserhaut um die Platte herumgeschlagen und auf der Handfläche der Platte vermittels eines Streifens, z.B. aus Aluminium, gehaltert werden kann, der auf der Innenseite der Glasfaserhaut angeordnet ist.
