发明名称 DOUBLE-WALL STRUCTURE
摘要 <p>A double-wall structure (1), comprising plate-like bodies (2) and (3) disposed oppositely to each other to form an inner room (4) therebetween, peripheral members (5) disposed so that the inner room (4) can be completely or approximately closed, and perforated plates (13) with a large number of holes (8) disposed between the plate-like bodies facing each other. The double- wall structure is characterized in that an air layer (A) is interposed between the perforated plates and the peripheral members. Thus, since the double-wall structure can suppress the deterioration of a sound reduction index for sound with specific frequencies, it can stably develop sound insulation performance for sound with the various frequencies.</p>
