ABSTRACT:
The invention relates to an apparatus and a method for determining the softness of a hygienic paper or textile with at least one ply, wherein an element (106) is arranged relative to a positionally fixed sample (P), with at least one ply, of the hygienic paper or textile such that it can move and is designed such that it can be adjusted with respect to the sample (P) with a penetration force (F) acting on the sample (P) being specified, wherein in the region of the oscillations being produced between sample (P) and the element (106), an oscillation sensor (116) is arranged which registers the noises produced during the relative movement of the element (106) acting on the sample (P).
