The first synthesis study for the community annoyance to several traffic noises was conducted from an in-depth survey in Korea from 2003 to 2007, which was reported by the authors in ICBEN 2008. Previous research has investigated the effect of exposure from single source and compared the response of Korean with that of European and Japanese. The response varies with different cultures as well as different noise sources. A large part of the population is exposed to combined noise from multiple sources, but there is no standardized method for assessing the effects of combined noise. Although many researchers have investigated the response from combined noise exposure, it has little been reported that the annoyance caused by combined noise exposure from aircraft and road traffic. The purpose of this study is to assess the effects of dominant noise source with relatively high sound exposure level on total annoyance and compare the total annoyance from combined noise exposure with annoyance from single noise exposure. The result of this research would be useful when the effects of the multiple noise sources should be considered to establish the standard, regulation,
and noise mitigation policies.
