With the improvement of living quality, people's desire for quiet living environment keeps increasing. In particular, complaints about the noise emission by constrcution equipments around residential areas take most part of the noise related complaints. In this study, noise marking obligation system for the high noise construction equipment have been proposed to reduce the noise level and protect the well-being of citizens. For this purpose, construction equipment used in the country were surveyed and compared with that of the European Directive/2000/14/EC. As results, 20 kinds of construction equipment were proposed for the obligated noise marking, while 13 kinds of construction equipment were proposed for the equipment subject to permissible noise level, thus the obligated noise marking and certification.

This study aims at proposing a sound and sustainable development direction of an residential environment by analyzing testimonies of residents who lived in Park Hill flats or their surround at Sheffield City in the United Kingdom. The results are obtained through the analysis on a residential environment of Park Hill flats, opinions of the residents on its refurbishment, and effects of the building on the residential environment. The block of Park Hill flats was a community with a strong unity and solidarity, but that became increasingly a slum by the decline of the physical and social environment since the 1980s. In particular, it was identified that the deterioration of the social environment than that of the physical environment was a major cause of the decline. Nevertheless, it was found that "streets in the sky", the concept applied in Park Hill, played a key role in activating the community in the apartment complex. However, that street system in the complex has caused noise, poor security, and invasion of privacy. If such problems are solved, the streets in the sky will be a meaningful alternative for community activation and then ensuring sustainability in Korean residential environments that lost the function of the community.

This study was designed to understand the residential experience of Korean women living in tropical country. For qualitative research, interviewees were selected by snowball sampling among Korean women living in Malaysia for over 20 years. The selection criteria for interviewees included husband's nationality, occupational experience, future living plan, frequency of travel to Korea. In-depth group and individual interviews were conducted from August 23 to October 7 2014. Subsequently (1) interviewees' general residential experiences in Malaysia were summarized, (2) interviewee's identity and lifestyle with housing pathways approach were clarified, (3) interviewees' residential experiences in 5 issues, reciprocity in residential area, intention of environmental change, meaning of housing and interaction, housing adaptation, and residential satisfaction/dissatisfaction were prescribed and interpreted. In conclusion, the reflection of interviewees' experiences in tropical country, suggested variations of housing structure type within a residential complex, air well and pocket by setback in building block for improving ventilation and noise prevention from neighbors, and ceiling fans in the house were suggested for the upcoming subtropical climate in Korea. Full option and minus options were also suggested for the presale market to reduce before occupancy remodeling needs. The research results implies valuable suggestions for a multicultural society, ecological housing and stronger communities.

The purpose of this study is to propose indoor noise level in residential buildings affected by transportation noise (road traffic, railway and air-craft noise) based on subjective evaluations, 30 subjects participated in the experiment to evaluate the noise. Experimental environment reproduced real living and office environment, and in asking subjects' annoyance to the noise. An experiment to investigate the subjective responses to various computer noises (CD-Rom, HDD, Fan) in office environment was also undertaken. The Result shows that the lower limit of transportation noise is $40{\sim}41dB(A)$ and upper limit is $55{\sim}60dB(A)$, whereas the lower limit of various computer noises is $36{\sim}40dB(A)$ and upper limit is $45{\sim}52dB(A)$.

The purpose of this study was to present the possible use of a new standard impactor, the rubber ball(so called, impact ball), and to assess its evaluation method as for heavy-weight impact in multi-story residential buildings, Several experiments were carried out to investigate the effect of the impact on noise propagation in reinforced concrete buildings. Then, the noise from the impact ball was psychoacoustically evaluated. The correlation between the L-value evaluation methods and auditory responses was also investigated. Results show that the ball noise is quite similar to the jumping noise. The noise level of ball is even higher than the bang machine noise, although it has much lower impact force. It was also found that L-indexing seems to bge inappropriate for evaluation of ball noise.

People in the advanced society have deep interest in such environmental problems as noise, air quality, water pollution, etc. This paper submits the result of the research on the noise In the surroundings of the butane can explosion location. First, the noise level measured in a residential area, 245 meters' away from the butane can explosion location, was 59.3 dB. Also, the noise level measured in the IGUP (International Graduate University of Peace), 300 meters' away from the explosion site, was 52.5 dB. Second, the above noise levels are lower than the level specified In the Environmental Standard (65 dB), which represented that the experiment was safe. Third, the noise level in a place away from the butane can explosion location varied in accordance with the direction of the wind. Consequently, the noise in all locations (the places where damage to people is expected) surrounding the experimental butane can explosion location was measured to identify the effect of the wind irection.

The purpose of the study is to analyze the existing situation of the green buffer zone in the large scale industrial site and other major residential apartment areas. In this study, it is specifically intended that the planning guideline be upgraded to adopt future landuse trends and thus to suggest design criteria for management of the buffer zone. The framework of the analysis is to review the current landuse, noise reduction, ecological implications and landscape in general. Although the major function of a green buffer zone is considered to protect the residential area from various hazards of industrial, traffic, and visual environment, the situation is that most of the zones are maintained at a minimum level of services by local government. The study carried out intensively almost every type of case studied throughout the country, which implies that the management of the green buffer zone should be expanded physically enough to function for its original objectives. The study recommends that ecological management of the green buffer zone be emphasized and therefore the criteria for this purpose as well as noise issue should be developed prior to the landuse aspects. The study suggests specific guidelines for planning and design for the green buffer zone development. This study should be verified positively through the sustainable monitoring and requires nationwide and overall examination so that it may be applied to whole green spaces.

Purpose: The purpose of this study is to examine the policy implications of establishing a compact city in Seoul, analyzing whether it is an appropriate and efficient eco-friendly housing supply alternative. Research design, data, and methodology: The analysis criteria include efficiency, safety, and comfort, with efficiency encompassing economic, energy, and public transport links' efficiency. Safety and comfort are aspects of eco-friendliness, housing safety, and improvement in living environments. Results: In terms of economic efficiency, compact cities are a less expensive option than purchasing land for housing construction. To increase energy efficiency, we plan to adopt eco-friendly energy sources. Transportation efficiency is high in locations near public transport stations. To enhance safety and comfort, we intend to create large-scale parks and forests in Seoul. To ensure residential safety, measures will be taken to reduce road vibration, vehicle noise, and scattering dust. Conclusions: Selecting an appropriate location that provides convenient public transportation is essential for creating a compact city for housing in a large city. Combining a compact and smart city is necessary, and implementing smart technologies is needed to prevent dust, noise, and vibrations, which are undesirable in a residential environment.

The urban railway has been planned not only the subway, but also the elevated railway in Seoul, South Korea. Therefore, it is steadily increasing civil complaints for railway noise passing through that residential district. In this paper, we focused on noise of squeal characteristics induced by interaction between railway vehicle's wheel and rail. Then we selected the point that carried out scattering water droplet to the rail and compared the noise level of the watering test results before and after. Scattering water test results showed that level of the noise reduced intermittently occurring high frequency characteristics of squeal noise as well as overall noise level. In the future, we will apply the sensor to the sprinkling system for noise reduction where the place of existing squeal noise is, and make a suggestion of this solution will be more economical, environmental-friendly, and appropriate to reduce the squeal noise occurred by railway vehicle than others.

The subjective unwantedness felt from the noise sources in living environment has been evaluated by investigating the limit of perceptual loudness of the noise. The noise limits were selected by the subjects. And the noises were analyzed to find out whether there is any correlation with Zwicker parameters and ACF/IACF factors. It seemed that the loudness of noise from vacuum cleaner does not affect its perceives noisiness. Traffic noise also seems to be less influential in annoyance rating. It was resealed that floor impact noise generated by bang machine is the most irritating noise that can be heard in residential buildings.
