Title:
FIBRE COMPOUND ACOUSTIC ABSORBING MATERIAL
Document Type and Number:
Japanese Patent JP2011197672
Kind Code:
A
Abstract:
To provide a sound absorbing (acoustic attenuation) material, the efficiency of which is improved.
The absorbing material 11 consists of a ground material that is composed of fibers that are in loose connection with each other. The fibers are minimally interlooped with each other or also glued to each other. This ground material is condensed in some areas in that the fibers are reoriented or interlooped with each other to a greater degree or glued to each other. Consequently, zones (17) and (18) of different densities are formed, thus making it possible to increase and adjust, as desired, the sound-attenuation effect of the absorbing material 11.
