Abstract

Bei einem schallabsorbierenden, schichtförmigen Schaumstoffmaterial, dessen dem Schalleinfall zugewandte Oberfläche mit Erhöhungen und Vertiefungen versehen ist, wird über dieses Oberflächenprofil eine Folie derart gespannt, dass sie im Bereich der Erhöhungen am Schaumstoffmaterial anliegt und in einem Abstand über den Vertiefungen verläuft.

Figure imgaf001
In a sound-absorbing, layered foam material whose surface facing the sound incidence is provided with elevations and depressions, a film is stretched over this surface profile in such a way that it rests against the foam material in the region of the elevations and extends at a distance above the depressions.
