Title: Sound insulation material
Inventor: NINOMIYA FUJIO
IPC: E04B1/86
Filed: 1995-05-15
Abstract: PURPOSE: To obtain a sound insulation material which can efficiently absorb noises even when lots of noise sources are present and generate noises of different frequency levels. CONSTITUTION: A sound insulation material 1 is attached to an engine room side of a hood panel of a car. This sound insulation material is made in a sheet form as a whole comprising a pulverized rubber layer 2 comprising pulverized rubber of various sizes, shapes and kinds, and coating layer 3 to cover the pulverized rubber layer 2. Noises are locally absorbed by lots of granular pulverized rubber itself and spaces in the pulverized rubber of the sound insulation material. Various noise sources such as an engine main body, sucking system or the like are housed in an engine room. However, since various sizes, shapes and kinds of pulverized rubber are mixed and each pulverized rubber has different frequency level for absorption from another, noises in lots of frequency levels can accurately be absorbed.
