A soundproof material for preventing noise and an installation structure of the same are provided to increase the installation performance and reduce the cost according to the formation of the soundproof member with the sound absorbing layer. A soundproof material(10) for preventing noise is composed of a base layer(11) made of the EVA or PE material; and plural recessed groove sound insulation units(12) which are conical recessed grooves(12a), consecutively formed at the surface of the base layer to prevent the noise from directly reaching the inner surface of the base layer. The noise transferred to the outside becomes vortex at an inner space(12b) of the recessed groove sound insulation units, is transferred to the inner surface of the base layer, and is blocked at the base layer to minimize the noise transfer. Plural lamination units(13) which are conical projections are formed to be stacked at the aerated concrete layer at the lower part of the base layer. |
