The invention relates to a silencer comprising an inner component and an outer component surrounding said inner component, said inner component defining an inner wall provided with openings and said outer component defining an outer wall extending along said inner wall. For improving the silencing characteristics as well as the flexibility of the silencer, the outer wall is implemented as a bellows which defines together with the inner wall individual cavities, the openings of the inner wall opening into said cavities. Furthermore, the outer wall is produced from a material having a density of at least 1.5 g/cm.

Silencer

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.
