There are many dispute with a construction due to such environment problem as vibration and noise. Generally, we have a standard for acceptance level in land. But we have not a sufficient standard for acceptance level or guide line in underwater sound. In other countries, a acceptance level or guide line in underwater sound has been suggested. Especially the management criterion of underwater noise for fish has bee suggested using the measurement data (peak pressure, rms, energy and SEL) by a hydrophone. In Korea, there is no management criterion of underwater noise for fish. This study suggested the management criteria of underwater noise for fish based on the measured data by a hydrophone.

본 연구는 현재 사회문제화 되고 있는 층간소음 피해 실태조사 분석을 통하여 적용 가능한 층간소음 분쟁의 예방을 위한 효율적인 관리시스템을 개발 적용하였다. 설문조사 분석결과, 층간소음의 주요 발생 원인으로 아이들 뛰는 소음과 어른 걷는 소음이 55% ~ 75%로 가장 심각한 소음원으로 나타났으며, 소음 피해시간대는 저녁(18시~22시) 시간대는 50% ~ 65%로 가장 높게 나타났으며, 야간(22시~ 06시) 시간대는 26% ~ 45%범위에 있는 것으로 분석되었다. 층간소음관리시스템 적용 전 후의 민원저감효과 분석결과, 전라도 광주는 100%, 대구시는 87.5%, 서울의 경우는 83%, 경기도는 71% 순으로 나타나, 평균 약 85% 이상의 민원 저감효과가 있는 것으로 나타났다. 층간소음관리시스템 적용 전 후의 아파트 가격 변화 분석결과, 적용된 아파트의 경우는 평균 17.23백만원 상승한 반면, 미적용된 아파트는 0.55백만원 하락한 것으로 평가되었다.

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.

The main purpose of this paper is to suggest a spatial planning approach to effectively deal with airport noise problems in neighborhoods adjacent to civil airports. Rapid urbanization around the airports, as well as growing concerns on quality-of-life, resulted in ever-growing airport noise complaints, lawsuit, and central government's financial burden. S. Korea government adopted a restriction- and compensation-based airport noise management policy against the problems in mid 1990s. It, however, turns out to be ineffective in guiding incompatible land uses and facilities away from the airports' environs and to encourage compatible ones to locate around the airports. Base on the United State's and United Kingdom's airport noise management practices, therefore, this study suggests a new spatial planning approach that emphasizes the following: 1) diversification of current airport noise mitigation programs, 2) introduction of "sector"-based, spatial management system, and 3) central government's close cooperation with local governments and communities.

The noise management in the interior of the power plant is difficult because the interior is large and the noise level varies greatly from location to location. Therefore, a noise visualization system capable of analyzing the noise distribution is required in order to effectively manage the interior noise. A noise mapping system was developed that can model the inside of the turbine room and create a noise map by measuring the noise level at selected points. And in order to increase the reliability of the model, the model was modified through a method of comparing the noise map and the actual noise measurement results. Facility abnormalities can be determined through regular analysis of noise maps, and a method of effectively managing the interior noise is presented by comparing and analyzing the frequencies and levels of the current and previous noise at a specific point. By using the mapping system, it is possible to establish noise countermeasures that can improve the working environment, check the machine for abnormalities, and increase the reliability of the facility through preventive maintenance.

Although the environmental conflicts regarding noise and vibration are continually increasing during construction, noise and vibration occurring in construction are only managed in construction phase. Noise and Vibration occurring in construction are considered to be insufficient, so we find that noise and vibration management in design phase has to be operated for reducing. The objective of this paper is to present noise and vibration management lists to consider in design phase for enhancing efficiency in noise and vibration management and to develop the appraisal sheets for designers to evaluate and the manuals to easily use management lists. To achieve this, we identify the noise and vibration management lists to consider in design phase through analyzing the previous literatures and confirm the 9 lists through conducting a research with experts in environmental area for verifying the propriety of lists. Also, this study applies to AHP technique to identify the priority and the weight evaluation among the lists. Through this study, we identify the most efficient lists, including from the low noise and low vibration methods, the noise and vibration reduction by blasting works, the installment and the arrangement of noise and vibration control equipments, for noise and vibration management in design phase. The achievement of this study will help to prevent the environmental disputes and conflicts in advance and will consider utilizing for the successful construction project.

지난 '91년부터 2000년까지 환경분쟁조정위원회에 접수된 분쟁사례 가운데 소음ㆍ진동분야가 78％를 차지하였으며, 특히 2000년도에는 85％에 달하여 소음ㆍ진동문제가 심각해져 가고 있다. 소음ㆍ진동규제법은 '90. 8. 1 환경보전법에서 분리되어 개별법으로 정비되었으며, 소음ㆍ진동 발생원별로 합리적인 관리와 규제를 함으로써 모든 국민들이 정온한 환경에서 생활하게 하려는 취지아래 제정되었다. (중략)

이 연구에서는 고속도로 신설 공사 건설 현장 근로자들의 소음 노출을 저감할 수 있는 방법들을 제시하며 특히 현장에서 적용할 수 있는 새로운 체계적인 방법인 "소음 주의 구역"을 제안한다. 고속도로 건설 현장에서 소음원이 되는 장비, 기계, 도구와 근로자들의 소음 노출 특성을 알아 보았으며, 개인청력 보호구, 공학적제어수단 (engineering controls), 관리적제어수단 (administrative controls)을 어떻게 적용할 것인가를 제시하였다. 개인청력 보호구만으로는 소음 노출을 효율적으로 저감시킬 수 없음을 보였으며, 공학적제어수단은 기술적 및 경제적 문제로, 관리적제어수단은 공사 기간 단축과 같은 실제적인 이유로 해서 시행 되기가 어렵다. 따라서 이 연구에서는 실제적으로 적용할 수 있는 체계적인 방법으로서 "소음주의구역 (Noise Perimeter Zones)"을 새롭게 제안하였다. 이 "소음주의구역"은 높은 수준의 소음원이 존재하는 고속도로 건설 공사 현장에 지정된다. 이 구역안에서는 근로자들의 출입이 통제되며 또한 개인청력 보호구, 공학적제어수단, 관리적제어수단과 같은 적절한 제어수단이 사용되어야 한다.
