摘要

The sound insulating panel (SP) has a first slot structure (VN) in the front side and a second slot structure (RN) in the rear side. The rear side along the panel edge has an encompassing edge section (RA) not broken by the second slot structure, and/or at the openings formed by the crossing points of the slot structures the width of the slots of the second slot structure is at least 50% larger the width of the slots of the first slot structure, and/or the openings in adjacent slots of the first slot structure are relatively offset in the direction of the slot course.
