The invention concerns a device for a door seal against sound in lift cages 1 with automatic doors. These doors normally display small air gaps between door post and door leaf 3, abutment 1.2 and door leaf 3, inner door leaf and outer door leaf in the case of telescopic doors and between door sill 5 and underside of the door leaf in order to avoid a contact between moved and fixed parts in the case of door movements. Vertical post seals 7 closing an air gap, abutment seals 10 sliding on the upper side of the door leaf 3, sills seal 6 in the door seal 5 and vertical door edge seals 3.1 at the front edges of the door leaves are present at the door leaves 3 for the sealing and covering of these air gaps in the closed state of the door. These seals close all air gaps all round when the door is closed and so largely prevent the ingress of sound of the noises produced mechanically outside the cage.
