SPACE-PARTITIONING PANEL

摘要

Disclosed is a partition panel (1) capable of improving sound insulation performance and optimizing a reverberation time in a room with no loss of consistency in a wall surface. The partition panel (1) has sound absorption and insulation functions, comprising: a front plate (2) having a perforated section (2a) with a plurality of through-holes and an entirely-continuous peripheral edge portion (2b) located outside the perforated section (2a); an entirely-continuous back plate (3) disposed on a side opposite to a sound source across the front plate (2); an inner perforated plate (4) disposed between the perforated section (2a) of the front plate (2) and the back plate (3); a front-side honeycomb core (5b) interposed between the perforated section (2a) and the inner perforated plate (4); a back-side honeycomb core (5c) interposed between the back plate (3) and the inner perforated plate (4); and a peripheral honeycomb core (5a) interposed between the peripheral edge portion (2b) of the front plate (2) and a region of the back plate (3) opposed to the peripheral edge portion (2b).
