[origin: JPH06208386A] 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.

Luftschalldämpfer, bestehend aus einem offenporigen Schaumstoffkörper (1) der brettähnlich gestaltet ist, wobei in dem Schaumstoffkörper (1) zum Zusammenstecken mit einem anderen, gleichartig ausgebildeten Schaumstoffkörper (2) zumindest eine Durchbrechung (3) vorgesehen ist, die in einer Seitenfläche (1.1) mündet. Die Durchbrechung (3) weist eine Höhe (4) auf, die etwa der halben Höhe (5) des Schaumstoffkörpers (1) entspricht. Die Tiefe (6) der Durchbrechung (3) entspricht der Dicke (7) des Schaumstoffkörpers (1). <IMAGE>
