Beschreibung
Zusammenfassung:	The present invention relates to a sound absorber comprising an inner component and an outer component surrounding said inner component, said inner component defining an inner wall provided with apertures, and said outer component defining an outer wall extending along said inner wall. For improving the sound-absorbing properties as well as the flexibility of the sound absorber, the outer wall is implemented as a bellows which, together with the inner wall, defines individual cavities, the apertures of the inner wall opening into said cavities.
