Abstract

Ein flächiges schallabsorbierendes Element besteht aus einer Platte (10), in der eine Vielzahl von Löchern als Mikroschlitze (20) verteilt beabstandet angeordnet sind, wobei jeder Mikroschlitz (20) eine längliche Form hat. Dabei weist jeder Mikroschlitz (20) die Form eines Kegelstumpfes mit schrägen Seitenwänden (21) auf, die die untere kleinere Lochöffnung (22) mit der oberen breiteren Öffnung (25) verbinden, wobei die untere kleinere Lochöffnung (22) eine Breite zwischen 0,05 bis 0,15 mm und eine Länge zwischen 10 und 60 Millimeter aufweist.
