One of the main objectives of noise control act is to define and ensure application and respect of noise exposure limits. Most advanced countries have prepared a legal framework for noise limits either by national laws, ordinances or municipal by-laws. A large number of advaced countries have adopted the Leq index for the main sources of noise(road, railway, industry). The exception is aircraft noise for which regulatory practice is highly disparate. These differences in the indices adopted, the periods and areas to which regulations apply, definitions of measurement conditions and ways in which noise levels are calculated make it difficult to compare the current advanced countries standards. This study presents the current noise abatement policy of the advanced countries and proposes the improvement of the current noise abatement policy of Korea to catch up with it of the advanced countries.

이동의 편리함과 주행안정성을 주기 위해 개발된 도로가 소음을 발생시켜 운전자 및 소비자의 쾌적성을 저해하는 요소로 작용하고 있다. 이러한 문제를 해결하기 위해 연도거리확보 또는 방음벽 등의 소음억제 방법을 사용하고 있으나 미관을 저해하고 용지사용이 비효율적이어서 외국의 경우 저소음 포장 연구를 통한 근본적은 소음 발생원을 차단하기 위한 노력이 진행되고 있다. 국내에서도 신도시 개발 등으로 도로건설에 따른 급속한 교통량 증가 및 차량의 고속주행으로 인하여 도시소음의 주요인으로 부각되고 있고 시민들의 높은 생활수준과 소음 환경에 대한 기본생활권 추구 성향이 증대되어 지역 주민의 교통소음 저감 대책 및 보상에 대한 법적 소송이 빈번히 발생하고 있어 차량 주행 소음 저감을 위한 방법으로 방음벽 설치가 널리 사용되고 있으나 이는 경제적 손실뿐만 아니라 도시미관을 해치는 문제가 발생하고 있다. 도로사업의 환경성 강화는 국토해양부의 2009년 주요도로정책 중 하나일 정도로 국가정책의 중요한 지침으로써, 향후 추진되는 신도시 및 단지조성공사 시 도로 환경성과 소음, 진동, 그리고 생태통로에 대한 친환경 도로설계 및 시공 등에 적절히 대응하기 위하여 교통소음을 개선하기 위해서는 교통소음 발생 요소를 파악하고 신도시 및 단지조성시 주변도로에 친환경적 포장공법 설계기술의 개발 및 적용을 위한 단계적 연구가 필요하다. 따라서 본 연구에서는 친환경 저소음 포장공법의 종류에 대하여 알아보고자 한다.

The development in air transport increases noise around the airport. In order to reduce the noise around the airport, International Civil Aviation Organization has made a lot of effort since the 1970s and Many countries, including South Korea, are implementing many noise reduction policies. This paper investigates those noise reduction policies of medium-sized airports with similar frequency to Gimpo, Jeju and Gimhae airports in South Korea and compares eleven airports in Europe, eleven airports in Asia and five airports in America, including Oceania. According to the research, European countries developed and applied the navigation procedure to avoid the noise area according to the characteristics of the airport. In Asia, there are not as many domestic noise reduction policies. In case of the United States, it provides information only on noise-sensitive areas around airports. After having investigated various policies, this research has examined the noise reduction policy of South Korea. It is concluded that new navigation procedures which reduce noise should be developed.

This study presents plans to prevent environmental noise by using noise maps when establishing development projects and targets strategic environment assessments for urban master plans and environmental impact assessment for urban development projects. Strategic environment assessments for urban master plans include the examination of plan validity and location appropriateness in consideration of the effect of environmental noise by comparing development plans with noise maps, and the establishment of long-term measures through comprehensive assessment of present noise conditions and noise effects from development plans. Environmental impact assessments for urban development projects propose enforcement plans, including analysis of present noise conditions around development areas, overall evaluation of present noise conditions and the noise effect from development projects, and selection of optimal measures by comparing noise maps with various alternatives.

Recently, many people have been damaged seriously by construction noise. Accordingly, there have been increased the complaints and disputes. These complaints should be controlled strictly. Otherwise there could be delays or stops of project and losses of time and money. For this reasons, the Korean government is trying to convert from depending on the soundproof wall to noise control system focusing on noise sources. However, it is difficult to control the noise which is generated from construction site because construction equipment has very high noise level and construction noise generates temporarily and irregularly. Also, people do not know how much low frequency affect human body adversely because they cannot perceive low frequency noise easily. Hence, recently developed countries have conducted the research on the low frequency noise which damages on human physically and mentally. However, passive noise control is insufficient to reduce the low frequency noise, but only efficient to lower the high frequency noise. Thus, an approach which can complement limitations of passive noise control is needed. Therefore, the purpose of this research is to suggest the noise management model using active noise control on construction site. Also, ANC simulation has been conducted to examine its applicability on construction equipment. As a result, it is expected that there will be a reduction of construction noise and demages, as well as both mental and physical damages.

To install and operate the Automatic Noise Monitoring Networks reasonably, which able to monitoring environmental noise continually, is an important issue for making decision to urban environment. Noise level is determined by regional environmental factors, that affected by complex urban environment. Therefore, accurate measurement of environmental noise level has top priority to establish and promote appropriate environmental policies. Currently, Automatic Noise Monitoring System is installed for grasping the environmental noise level and preparing basic data for constructing noise-reduction policies. However, this measurement data is recognized not to be able to reflect a sensory noise. The main reason is the lack of reliable measurement data and unreasonable installation site. The main point of this research ought to be the analysis of installed site of noise monitoring system in Busan.

In new housing demand, proportion of occupied multi-housing is 89.9% (statistics from 2013). In this way, with many generations living together, apartment noise disputes between the neighbors are continuously rising. The apartment noise problem in Korea is at a very serious level worldwide (about 88% of the population is experiencing stress due to apartment noise). On the other hand, the government has strengthened the regulations (such as the thickness of the floor and floor impact sound reduction performance, etc.) and promoted a resolution of its own for each multi-housing estates for mediating disputes on apartment noise. However, such physical regulations and passive management policies still presents a limit to the dispute mitigation of apartment noise. Also, in order to improve the quality of life in living spaces, policy on health effects of apartment noise should be provided. Therefore, we investigated a case study of the noise exposure-human body reaction to analyze the effect of noise on health. On the basis of this, the health effects according to the exposure period of apartment noise were considered.

Recently, there has been a growing global interest in environmental conservation, and the field of electric power equipment has been working to become more environment-friendly. Accordingly the 154[kV] low noise transformer is developed through the research. The low noise transformer decreases the audible noise level but the low noise transformer has several changes in the increase of weight and volume and the application of rubber damper. Therefore it is necessary to inspect the test, transportation, installation and operation about field application. In this paper, we investigate the standards of the audible noise level, the weight and volume of the transportation, the installation space and operation in order for effective field application.

Recently, the problem of noise has received much attention in the urban environment. This paper attempts to measure the economic benefits of urban noise reduction in the metropolitan area. To this end, the dichotomous choice contingent valuation method is applied. In particular, recently proposed one and one-half bound model that reduces the potential for response bias in the double bound model while maintaining much of its efficiency. We surveyed a randomly selected sample of 800 households in the metropolitan area and asked respondents questions in person-to-person interviews about how they would willing to pay for the noise reduction. Respondents overall accepted the contingent market and were willing to contribute a significant amount (997 to 1,778 won), on average, per household per month. This willingness varies according to individual characteristics such as concerns about noise, dwelling area, and income. The aggregate value of the noise reduction in the sampled metropolitan area amounts to approximately 79.26 to 141.35 billion won per year.
