PROCEDE D'ATTENUATION DE L'AMPLITUDE DE L'ONDE DE PRESSION RAYONNEE PAR LA SURFACE D'UN MATERIAU SOUMIS A DES VIBRATIONS D'ORIGINE MECANIQUE ET/OU ACOUSTIQUE AU NIVEAU D'UNE SURFACE INCIDENTE OU REFLECHIE PAR CETTE DERNIERE

摘要

A method for reducing the amplitude of vibration and the pressure wave (6) from a radiating surface (5) and/or an incident surface (3) of a material exposed to mechanical and/or acoustic vibration. The material consists of an anisotropically shaped heavy resilient structure with an internal geometry capable of deflecting and localizing vibration (7) within the structure. A specific material may be incorporated into the areas where vibrational energy is localized in order to convert the vibrational energy into another form of energy.
