Zusammenfassung: | PURPOSE: To satisfactorily fit a noise absorbing member to respective use examples and to obtain a satisfactory use characteristic by relatively enlarging a noise absorbing area against a structure dimension in the noise absorbing member constituted of the foam material body of continuous foams. CONSTITUTION: The foam material body 1 is constituted in a board form. For inserting the other foam material body which is similarly constituted into the foam material body 1 so as to connect them, at least one transparent opening part 3 opened to a sides 1, 1 is provided. The transparent opening part 3 has height 4 equivalent to almost half the height 5 of the pertinent foam material body 1 and has depth 6 equivalent to the thickness 7 of the pertinent foam material body 1. |
