Soundproofing used to insulate sound producing devices or parts of systems, especially devices that transmit variations or vibrators, comprising insulating elements (3, 3a, 3b) that are provided with an inner rim in the direction of the sound source and an outer rim in the direction away from the sound source. A damping diaphragm (4) which is made of a textile material and, more particularly, at least partially consists of glass fibre threads and/or woven wire, is arranged in the region of the inner rim. A solid flat material (9) is introduced into the region of the outer rim. A soft insulating material (7) consisting of a number of cavities is arranged between the solid flat material (9) and the damping diaphragm (4). The inventive insulating element offers optimal usage of all three elements, i.e. damping diaphragm (4), insulating material (7) and at least one reflecting surface on the solid flat material (9). The overall effect should not simply be seen in terms of three superimposed individual effects. The combined inventive arrangement of three elements and the configuration of the damping diaphragm thus described offer more than the sum of the invidual effects. |
