Conclusion 1 The model used for house pricing in this stydy is 2 Noise problem from Suvarnabhumi airport can be  reflected from a difference between prices of houses  inside and outside noise contour    1103370 Baht 3 Other attributes which may not be valued directly or easily can be determined by the calculation of marginal prices from hedonic price function in the 1 st  stage. ln(P) = 13.82 + 0.009LOT + 0.31FLOOR + 0.27BATH – 0.18BED – 0.27D1– 0.19D2
