Abstract

PURPOSE:To improve sound absorbing performance while providing a remarkably light sound absorbing material by providing integrally a net-like material defining at least one surface of a base material constituting a sound absorbing material on the surface. CONSTITUTION:In a sound absorbing material applied to a dash panel or the like for partitioning an engine room from a compartment of an automobile, a thin leaf-like light material is used for the base material portion of sound absorbing material having sound absorbing performance, while the sound absorbing performance is improved by defining and fractionizing the surface of base material by a resin net or the like. For the thin leaf-like base material are used foam material and film made of polyurethane, polyethylene, poly carbonate, etc., or fiber substance of felt or the like. The base material and material defining the base material surface are made integral by methods for applying adhesives on one surface of the material defining the base material surface and then bonding the material to the base material with pressure.
