The present invention relates to a rotor chamber for a centrifuge, in particular an air-cooled laboratory centrifuge, having a chamber wall, comprising an inner side facing toward the chamber interior, the chamber interior being implemented to receive a centrifuge rotor, and an outer side facing away from the chamber interior, and having a sound barrier which is implemented to reduce the sound emitted from the rotor chamber, which comprises a multilayer damping lining. The first layer comprises a material having essentially sound-absorbing properties relative to the second laver, and the second layer comprises a material having essentially sound-reflecting properties relative to the first layer. The present invention also relates to a centrifuge having such a rotor chamber, and methods for reducing the sound emanating from the rotor chamber of a centrifuge, in particular an air-cooled laboratory centrifuge.

1. A rotor chamber for a centrifuge having a chamber wall, comprising an inner side facing toward the chamber interior, the chamber interior being implemented to receive a centrifuge rotor, and an outer side facing away from the chamber interior, and having a sound barrier situated on the chamber wall which is implemented to reduce the sound emanating from the rotor chamber, wherein the sound barrier is a damping lining covering at least a subarea of the chamber wall and having at least one first layer and one second layer, the first layer and the second layer being situated lying at least partially flatly one on top of the other, with the first layer comprising a material having essentially sound-absorbing properties relative to the second layer, and the second layer comprising a material having essentially sound-reflecting properties in relation to the first layer. 2. The rotor chamber according to claim 1, wherein the first layer is situated pressing flatly directly on the rotor chamber on its side facing away from the second layer. 3. The rotor chamber according to claim 1, wherein the damping lining is situated on the outer side of the rotor chamber. 4. The rotor chamber according to claim 1, wherein the damping lining comprises at least two individual segments in its entirety, which are situated without overlap and particularly opposite to one another on the chamber wall. 5. The rotor chamber according to claim 1, wherein the damping lining is situated in the upper area of the rotor chamber. 6. The rotor chamber according to claim 5, wherein the damping lining is situated in the upper half of the rotor chamber. 7. The rotor chamber according to claim 1, wherein the damping lining annularly encloses the rotor chamber. 8. The rotor chamber according to claim 7, wherein the damping lining annularly encloses the rotor chamber coaxially to the rotational axis running through the rotor chamber. 9. The rotor chamber according to claim 1, wherein the second layer has a higher density than the first layer. 10. The rotor chamber according to claim 1, wherein the first layer has a layer thickness between 2 and 30 mm. 11. The rotor chamber according to claim 10, wherein the first layer has a layer thickness between 5 and 20 mm. 12. The rotor chamber according to claim 1, wherein the first layer essentially comprises a foam material. 13.

The rotor chamber according to claim 1, wherein the second layer has a weight per unit area of 0.5 kg/m2 to 6 kg/m2. 15. The rotor chamber according to claim 14, wherein the second layer has a weight per unit area of 1.5 kg/m2 to 4 kg/m2. 16. The rotor chamber according to claim 1, wherein the second layer essentially comprises ethylene-propylene-dyne rubber (EPDM), ethylene vinyl acetate (EVA), polyurethane (PUR), or polyvinyl chloride (PVC). 17. The rotor chamber according to claim 1, wherein the damping lining has a self-adhesive coating, which is implemented to fix the damping lining on the rotor chamber. 18. The rotor chamber according to claim 17, wherein the first layer of the damping lining has a self-adhesive coating, which is implemented to fix the damping lining on the rotor chamber. 19. The rotor chamber according to claim 1, wherein the chamber wall has an edge implemented pointing away from the chamber interior in the upper area of the rotor chamber, which protrudes beyond the damping lining in the radial direction. 20. A centrifuge having a rotor chamber according to claim 1. 21. The centrifuge according to claim 20, wherein the rotor chamber is received, at least in its base area in a molded part, which essentially comprises a sound-reducing material. 22. The centrifuge according to claim 21, wherein the rotor chamber is seated in the molded part in such a way that the molded part and the damping lining are free of overlap in the axial direction. 23. The centrifuge according to claim 20, wherein the centrifuge comprises an air-cooled laboratory centrifuge. 24. The rotor chamber according to claim 1, wherein the centrifuge comprises an air-cooled laboratory centrifuge.
