Patent abstract
A sound absorber includes an inner component and an outer component surrounding the inner component, the inner component defining an inner wall provided with apertures, and the outer component defining an outer wall extending along the 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 the cavities.
