Hi Paul,
    How about f(w1, w2, w3, w4, f, ft, c):
w1 = wall 1 distance
w2 = wall 2 distance
w3 = wall 3 distance
w4 = wall 4 distance
f = floor distance
ft = floor type, i.e., (cement, cement with rebar, wood over soil, soil, rock,
                               copper screen, aluminun sheets, desert dry
lake bed)
c = ceiling distance

Cheers,

Barry
