Aviation noise from Bangkok Suvarnabhumi airport has severe impact on the quality of life of peoplewho live in surrounding areas since the airport began operation in 2006. Although the airport authorityoffered to buy homes in the most severely affected areas or to provide funds to soundproof them, thecompensation program was aimed mainly at homeowners, but not renters of apartments or dormitories.In previous studies in Thailand, the focus was also on examining the noise depreciation of homevalues, by hedonic price modeling. In this paper, we broaden the scope of previous research to includethe noise impact on renters by using contingent valuation method to examine their Willingness toAccept Compensation (WTA) when the noise level increases. The estimation of WTA was based onchoice experiment, in which the subject was asked to evaluate alternatives in hypothetical scenarios,and select their most preferred alternative. We use experimental design technique to systematicallycreate alternatives with different levels of flight frequency and amount of compensation in eachscenario in order to study trade-off behavior between these attributes. Coefficient estimates ofmultinomial logit model imply that the WTA for an increase of one flight movement ranges from 18.87to 68.62 Baht (US$0.63 to 2.29) per month. The results of this study can be useful for informing theairport authority's noise compensation policy, which needs to be revised in the near future, in light ofits plan for the airport's expansion.
