Urban residents in crowded complexes are making increasing civil complaints about noise and demanding pleasant and comfortable residential environments. Because noise is one of the most important factors related to urban residents' dissatisfaction with their living environments, the present study investigates the direct and indirect effects of noise-related outdoor environmental factors on residential level satisfaction, using noise level data from 29 noise-measuring stations in Seoul. From 62 multi-family apartment complexes near these stations, the authors collected GIS-based environmental attribute data, as well as survey data including the residents' personal characteristics and indicators designed to measure latent psychological characteristics: noise sensitivity and residential noise level satisfaction. This study then utilized structural equation models to analyze the direct variables influencing the latent variables of noise sensitivity and residential noise level satisfaction, as well as the complex relationships among all variables. The result showed that residents who are exposed to less noise, possibly due to living in apartments facing relatively quiet roads, protected by soundproof walls, or surrounded by densely planted trees, tend to be less noise sensitive, which makes them more satisfied with the ambient noise level. Therefore, critical outdoor environmental variables can be used to reduce noise sensitivity and improve residential noise level satisfaction.

A survey and auditory experiment on multiple residential noises such as floor impact, airborne, bathroom, drainage and traffic noises were conducted to develop a combined rating system and to establish criteria for multiple residential noises. Subjective reactions such as annoyance, activity disturbance, sleep disturbance, and satisfaction to overall noise environment and each residential noise were recorded. The effect of individual noise perception on the evaluation of the overall noise environment was also investigated. The survey results showed that satisfaction for floor impact noise most greatly affects the overall satisfaction for overall noise environment and annoyance most greatly affects the satisfaction for individual noise sources. Auditory experiments were undertaken to determine the percent satisfaction for individual noise levels. Result of auditory experiment showed that the noise level corresponding to 40 % satisfaction is 49 dB $(L_{i,Fmax,AW})$ for floor impact and is about 40 dB(A) for airborne, drainage and traffic noise. From the results of the survey and the auditory experiments, an equation for predicting the overall satisfaction for multiple noises was developed and a classification of multiple residential noises was proposed.

A 7-point verbal noise annoyance scale for residential noises was developed in this study. An auditory experiment using major residential noises such as air-borne, bathroom drainage, and traffic noises was conducted to develop a noise annoyance scale for rating residential noises and allowable limit of them. The modifiers used in the scales were selected according to the method proposed by ICBEN(international commission on the biological effect of noise) Team 6. Results showed that the intensity of the selected words in the 7-point noise annoyance scale was highly correlated with noise levels. and that the intensity difference between each pair of successive levels in the 7-point annoyance scale was almost identical. The allowable limit of residential noise was also investigated in the auditory experiment and that of airborne, drainage and traffic noises were 42.3 dB(A), 41.0 dB(A) and 42.7 dB(A), respectively.

It seems inevitable for residential buildings to be high-rise and allocated near traffic roads due to the overcrowding in urban area. Acoustic environment in those residential buildings has been seriously deteriorated by the increase of traffic vehicles. Commonly used sound barriers have a limitation in controlling noise diffracted over the boundary of a sound barrier and hence are not effective to attenuate noise especially for the residential units in high level. The use of an enclosed noise barrier can be an alternative to supplement the defects of conventional noise barriers. The present work aims at providing useful data in designing enclosed noise barriers for residential areas adjacent to roads. Number of field measurements for various noise barriers and enclosed noise barriers were carried out and the results were discussed with relation to the proper design of enclosed noise barriers.

교통소음공해가 도시생활에 있어서 건강에 중요한 영향을 주고 있으며 소음을 효과적으로 측정하기 위해 소음분포에 관한 소음지도제작은 매우 긴요한 일이 되고 있다. 도시교통소음지도는 소음을 조정하기 위한 효과적인 방안을 찾고 실질적인 근거를 마련하는데 도움을 주고 있으며, 소음이 도로로부터 주거지역으로 어떻게 전파되는지를 시각적으로 이해하기 쉽게 정보를 주고 있다. 본 연구에서는 도로와 거주지역간의 개발형태를 3가지로 구분하여 고려하였고, 주거지역내에서의 필지별 소음정도를 도로로부터 거리가 떨어짐에 따른 소음감쇄를 ArcGIS의 보간법을 적용하여 계산하고 그 결과를 이용하여 소음지도를 제작하였다. 그 결과 주거지역내의 교통 소음수준이 국내 환경기준을 초과하고 있음을 알 수 있었고, 각각의 필지별 소음수준을 추정할 수 있었다. 이것은 향후교통소음조정계획을 수립하거나 공시지가평가 시 활용될 수 있을 것으로 판단된다.

Environmental noise in the residential area is appeared with different types and features along with the growth of society. In particular when the economic level is raised up, the demand of residents for the environmental noise becomes more sensitive. The existing research on the environmental noise was initiated in the 1980's and resulted that the children's jumping sound was most annoying among the noises transmitted from the other unit. This result caused such activities that the researches were focused on the floor impact noise and that the laws in relation to environmental noise within residential area were revised strictly. This study aimed to survey the consciousness of residents for the environmental noise and to see how it is changed comparing with the previous one. Ultimately this result could be useful to establish the target for research or noise control to make the comfortable residential environment.

This study was performed for make the plan of large residential zone considering reduction of the traffic noise and landscape, to meet the demand of resident who pursuit the amenity. For the first time, suitable traffic noise prediction model was selected and modified. Also, quantitative analysis of the traffic noise reductor was performed. These results are utilized plan of large residential zone efficiently.

Social survey and auditory experiment on residential noises such as floor impact, air-bome, bathroom, drainage and traffic noises were conducted to investigate the effects of sensitivity and background noise levels on subjective response to residential noises. Results of survey showed that multiple questions for sensitivity to noise have a more power for discrimination against subjective response to noise than single question. It was also found that the correlation between sensitivity and annoyance was relatively low, but the differences in annoyance between sensitivity groups were significant. Result of auditory experiment showed that effects of sensitivity on annoyance were different according to noise type and noise level. It was also shown that the difference in annoyance between the lowest sensitive stoup and the highest sensitive group was significant in low noise level. The effects of background noise on subjective responses to noise was also different according to noise source and noise level, and were significant in low noise level of airborne and drainage noise.

The floor impact noise arising between upper and lower households in residential houses has been known as one of major causes worsening residential environment and still led to serious social troubles in a residential community. It is known that the heavy weight floor impact noise is induced by flexural vibration modes in the relatively lower frequency ranges. In this study, a procedure is examined to evaluate the relations between the vibration modes and the corresponding noise of the slab. In the process, for simplicity of the numerical analysis, it is assumed that the slab is simply supported plate-like structure and the acoustic mode formed in the lower room by acoustic boundary conditions is ignored.
