The invention relates to a component for sound absorption and air conditioning (2), which is characterized in that a sound-absorbing planar structure (1) is coated with photocatalytically active material that can be irradiated by UV light sources (3), wherein the air can be guided along the planar structure (1) and/or through the planar structure (1). The component thereby has a front side facing towards a room (5) and a rear side facing away from a room, the rear side being coated with photocatalytically active material.
