摘要：
The invention concerns a reinforced concrete element comprising an at least partially open-cell foamed, sound-absorbing material which is partially exposed on a surface of the concrete element. The surface on which the foamed material is exposed consists only partially of the foamed material and the reinforcement is partially surrounded by the foamed material. The invention further concerns a method of producing the concrete element and the use thereof as an acoustic ceiling in a building.
