に関する。[Detailed Description of the Invention] The present invention provides noise prevention for steel plate parts of vehicles, etc.
In more detail regarding the method, an uneven shape is formed on a 7-ohm synthetic resin foam plate, and a heavy scraping is applied to the protrusion.
After that, the surface is applied so as to be in contact with the steel plate surface of a vehicle, etc., and the noise level in the 1° frequency range is 11. The present invention relates to a noise prevention method for vehicles, etc., which achieves the following effects: 1) and υ゛reducing the overlap of soundproofing materials.

１旧こ重ｉ１１が増加ｒる問題がある。As a noise prevention method for Shinryogo, a viscoelastic material is used by mixing fibrous and powdery fillers into the steel plate parts of vehicles, bituminous materials, and molding them into a sheet shape by heating and fusing them. However, since the desired portion of the steel plate is heated and melted over the entire surface, there is a problem that the heat content increases.

１こ了ｒケる。In view of the above circumstances, the present inventors conducted research and formed an uneven shape on the surface of the foamed 7-ohm foamed material for baking that is in contact with the steel plate, and impregnated the protrusions with heavy @1.1 scraping. d. By adding weight to some parts, the weighted parts act differently against the vibrations of the steel plate, and the phase shift of the vibrations caused by such movement reduces noise in the low frequency range. The present invention was achieved by discovering that: 111i 1. The gist of the present invention is as follows: Steel plate part 1 of a vehicle, etc.: A soundproofing method 1 in which a soundproofing material is applied to create unevenness on the surface of a 7-ohm material in contact with the steel plate part, which is made of a foamed synthetic resin. A method of soundproofing a vehicle etc. in which a shape is formed and a surface impregnated with a weighting agent is applied to a steel plate part of a vehicle etc. so that the convex part is in contact with the surface impregnated with a weighting agent.
