A device to reduce wind noises on elevator cars traveling at high speed consists of domes (1) with aerodynamically favorable shape which are attached above the car roof (3) or under the car floor (4) or in both places concurrently, these domes being made of an elastic, membranous foil. The stiffness of the domes is given by means of a supporting structure of rod-shaped elements, or by air chambers built into the membranous dome walls. Openings (9) in the dome walls, which can be fastened with zip fasteners, permit evacuation of passengers and access to the car roof and the underside of the car.
