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
・Young's modules of member(N/m^2)：E
・Second moment of area(m^4)：I
・Bending Rigidity(Nm^2)：B
・Diameter of circle(m)：φ
・Interval of void(m)：a
・Equivalent thickness is calculated as Poisson's ratio is zero.
