Definitions

  • a conventional mass-spring system typically provides attenuation in the range of 12-18 dB / octave.
  • the combination of the mass-spring system with the air cushion brings an additional attenuation in the range of another 2 to 5 dB / octave.
  • the heavy foil has at least the same, but preferably a multiple of the basis weight of the elastic film.
  • a sound attenuation mat 20th So that the noise level in the occupant cell 12 is as low as possible, there is a sound damping lining 21 in the sky and a sound absorbing carpet 22 on the floor pan.
  • the foot pedals 17, of heating cables and electrical lines 13 corresponding openings are provided in the sound insulator 23 and in the end wall.

Abstract

L'invention concerne un isolant pour l'insonorisation de l'habitacle d'un véhicule automobile, et a pour but de développer un tel isolant permettant d'obtenir un effet d'amortissement amélioré dans une gamme de fréquence inférieure à 300 Hz. L'invention a en conséquence pour objet un isolant pour l'insonorisation de l'habitacle d'un véhicule automobile, comprenant un coussin d'air présentant une enveloppe en un matériau élastique, efficace pour les amortissements, disposée entre un composant générateur de bruit et l'espace de l'habitacle, caractérisé en ce qu'il est prévu une couche d'insonorisation (25) adaptée à la forme dudit composant (13) et agissant en tant que système à matière élastique, ladite couche étant fermée, côté habitacle, par une feuille pesante (26) formant une première enveloppe du coussin d'air (29), et en ce qu'il est prévu une seconde enveloppe du coussin d'air (29), reliée de façon étanche avec ladite feuille pesante (26), constituée par une feuille élastique, de préférence préformée (27), formant entre la première et la seconde enveloppe, un coussin d'air (29).
