スト及び防音材の効果の点で改良の余地がある。As a prior art relatively similar to the present invention, a patent application publication No. 5-487 filed by Matsushita Electric Works, Ltd.
There is an invention described in No. 31. This prior art relates to a method of manufacturing a vibration-proof base material using a so-called synthetic leather waste material in which a vinyl chloride resin is laminated on a synthetic resin base cloth, and does not utilize a waste material of a backing carpet. Since the prior art is characterized by the fact that the synthetic resin base cloth and vinyl chloride are separated from each other in the manufacturing process, there is room for improvement in terms of cost and the effect of the soundproof material.

ないことと目的とする。The soundproof material which is the object of the present invention will be explained before describing the means for solving the above problems. Soundproofing is a general term for construction that blocks or absorbs sound and improves the acoustic environment in the room.The purpose is to prevent outside sound from entering the room, and to prevent the sound inside the room from propagating outside or downstairs. To do.

ビニルフィルム等膜状材料等が例示される。Sound absorption is a phenomenon in which when sound waves pass through a medium, a part of sound energy is converted into other energy by some conversion mechanism, and any material absorbs sound to some extent. Typical sound absorbing materials include glass wool, felt, foam resin material, porous plate exemplified by soft fiber board, porous plate structure such as porous plaster board,
Membrane materials such as vinyl film are exemplified.
【００１１】このように、遮音材と吸音材は、本来異な
る機構に基づくものであるので、両者を兼ねたものを、
安価に製造することは困難である。As described above, since the sound insulation material and the sound absorption material are originally based on different mechanisms, a material having both functions should be used.
It is difficult to manufacture at low cost.
