As the average noise level and number of noise sources have increased, governments have taken various measures to make soundscapes sustainable. Wise policy decisions require information about the monetary value of noise-control policies. This study elicited people's willingness to pay (WTP) for noise policies, separating traffic noise from residential noise to compare the value of controlling different types of noise. The contingent valuation method was used for the empirical analysis, with data from South Korea. The results show that the monthly mean WTP of respondents was KRW 3392.3 for residential noise reduction and KRW 3507.1 for transport noise reduction; thus, the WTP for the latter is slightly higher than that for the former. Moreover, about 80% of people are unwilling to pay for a noise policy at all, and that high ratio of people with zero WTP must be taken into consideration in the process of policy formulation and implementation. Respondents' experiential and psychological factors were found to be more important than their demographics in explaining their WTP for a noise policy. Potential policy implications based on the analysis results are provided.
随着平均噪声水平和噪声源数量的增加，各国政府已经采取了各种措施来维持声音环境的可持续性。明智的政策决策需要有关噪声控制政策货币价值的信息。本研究通过意愿支付调查（Contingent Valuation Method）来获取人们对噪声政策的支付意愿（WTP），将交通噪声与居住噪声区分开来，以比较控制不同类型噪声的价值。本研究使用来自韩国的数据进行实证分析。结果表明，受访者每月平均愿意为居住噪声降低支付 3392.3 韩元，为交通噪声降低支付 3507.1 韩元；因此，后者的 WTP 略高于前者。此外，约 80%的人根本不愿意为噪声政策支付任何费用，在政策制定和实施过程中，必须考虑到这种高比例的零 WTP 人群。研究还发现，受访者的经验和心理因素比其人口统计学特征更能解释他们对噪声政策的 WTP。本研究根据分析结果提供了潜在的政策含义。
