<p><P>PROBLEM TO BE SOLVED: To provide a soundproofing material for a pipe for improving soundproofing performance, while suppressing a cost increase and degradation of workability. <P>SOLUTION: The soundproofing material 1 for cylindrical pipe is provided around the outside periphery of a pipe 2 to reduce sound caused by supply and discharge of water. The soundproofing material is constituted so as to form voids 3 around the outside periphery of the pipe 2. The soundproofing material can be used as a slip-on type soundproofing material for a pipe, or a pipe-integrated soundproofing member. Thus, not only the soundproofing performance, but also suppress of variation in the soundproofing-performance and workability for the soundproofing structure are considerably improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
