The adhesive is formed on the entire contact surface between the sheet E and the metal exterior material D, or in a linear (plural) or planar (plural) horizontal, vertical, oblique, or the like. Of course, when the entire surface is formed with an adhesive, the solid sound generated when the metal exterior material D itself collides (in contrast to the sound propagating in the air is referred to as air sound), and the solid sound is generated. It is attenuated by the synergistic effect of the seat, and has the effect of preventing the intrusion of noise into the house indoors.

Further, the sheet E can be impregnated with, contain, mixed, laminated (one or more layers), sandwiched, etc., to provide the sheet E with sound insulation. Is in the form of powder, sheet, or the like.

Since the transmission loss representing sound insulation is substantially proportional to the weight per unit area of a wall made of a uniform material, the larger the mass per unit area, the better the sound insulation performance. . For this reason, a material having a large specific gravity is used as the sound insulating material formed on the sheet E.

As the sound insulating material, metal powder (lead, iron, copper, brass, etc.), concrete powder, cement powder, glass powder, rubber powder, etc., or metal plate (lead, iron, copper, brass, etc.) ,
Concrete board, cement board, glass board, rubber board, etc.
Or, stone powder, rock powder, gypsum powder, calcium carbonate, calcium silicate, and the like. Of course, a sound insulating sheet material in which these are formed into a sheet shape (combined with a synthetic resin, an adhesive, or the like) can also be formed as a sound insulating material.
