The partition 10 comprises a first region 110 and a second region 120 that is positioned at a lower part than the first region 110 when the partition 10 is erected on the floor face. The second region 120 has a higher sound absorption rate than that of the first region 110. <P>COPYRIGHT: (C)2013,JPO&INPIT |
