Centrifugal separator includes a rotor, which is arranged in a gas containing chamber and which on its outside surface is provided with a number of cavities located at a distance from each other and open to the chamber. In order to disturb the generation of sound waves in the cavities at the resonant frequency of the cavities, an irregularity, preferably in the shape of a projection, is arranged nearby and in front of at least one cavity in the rotational direction of the rotor.
