The invention relates to a floor panel (1) with sound-absorbing properties, comprising a carrier plate (2) which has an upper side (2a) and a lower side (2b), wherein the floor panel (1) has a plurality of cavities (3) which, starting from its upper side (1a), extend in the direction of its lower side (1b) and which completely penetrate the carrier plate (2), wherein each cavity (3) is subdivided into at least one upper portion (3a) and into exactly one lower portion (3b), wherein in each cavity (3) each upper portion (3a) extends from the upper side (1a) of the floor panel (1) to the lower portion (3b) and the lower portion (3b) extends from each upper portion (3a) to the lower side (2b) of the carrier plate (2) and wherein in each cavity (3) the cross-sectional area of each upper portion (3a) is smaller than the cross-sectional area of the lower portion (3b). The sound-absorbing properties are improved with such a floor panel (1). The invention also relates to a corresponding production method and to a corresponding production device. |
