Remarks

・Basic impedance level(dB):Lzb
・Basic impedance(kg/s):Zb
・Equivalent thickness of floor slab(m):h
・Density of member(kg/m^3):ρ
・Thickness of floor slab(m):h1,h2,h3
・Young's modules of member(N/m^2):E
・Second moment of area(m^4):I
・Bending Rigidity(Nm^2):B
・Breadth of void(m):b1,b2,b3
・Equivalent thickness is calculated as Poisson's ratio is zero.
