ANECHOIC CHAMBER
PROBLEM TO BE SOLVED: To provide an anechoic chamber suppressing deterioration of sound insulation performance and generation of background noise due to resonance of a heat insulating panel.SOLUTION: An anechoic chamber 1 has a heat insulating panel 13 and a sound insulating layer 14 provided inside the heat insulating panel 13. The heat insulating panel 13 is formed by filling a heat insulating material between an outer metal plate and an inner metal plate, which have different thicknesses from each other.SELECTED DRAWING: Figure 3
【課題】断熱パネルの共振に伴う遮音性能の低下や暗騒音の発生を抑制する無響室を提供する。【解決手段】無響室１は、断熱パネル１３及び断熱パネル１３の内側に設けられた遮音層１４を備えている。断熱パネル１３は、２枚の異なる厚みの外側金属板と内側金属板との間に断熱材を充填させて構成されている。【選択図】図３
