Abstract (en)
The three-dimensional sound damping material (13) has homogeneous mixture of same fiber or different fiber over its thickness. The sound damping material with in the area of the top side possesses randomly distributed outer micro reflection points (14) and inner micro reflection points (15). The inner and outer micro reflections points are formed in the area of the top side and by the randomly formed structures of the fiber profiles. An IDEPENDENT CLAIM is also included for method for production of the sound damping material.
