  • The guideline for railway noise mapping is notificated in the administration law for noise/vibration which is announced by the ministry of environment, Korea. Here input parameters for the railway sound sources are proposed for each prediction models. In case of the application of the vehicle characteristics it is suggested to choose "0(%)" for the disc brake parameter. However new trains have been in revenue service since the announcement of the guideline, an investigation of the effect of the input parameters of the foreign railway prediction models on the prediction results of korean railway systems are needed. In this paper the sound prediction results are analyzed with a focus on the input parameters such as disc brake percentage, rail roughness, rail joints. Schall03 is used for the railway noise prediction which has been using most frequently in Korea. The results are shown and discussed.

  • This study has been conducted for current situation of and countermeasures for aircraft noise. Aircraft noise is difficult to control, because of its wide-range effects, and it needs a great deal of funding for noise prevention like removal airport or land purchasing. And, in effort of determine whether aircraft noise can have health effects such as hearing loss, hypertension and psychological stress. This study, which uses of noise data around flight training airports in Korea, tries to understand and confirm related laws and regulations, and present civil application and situation of countermeasures. And, by measuring data of flight training airport, the situation of training aircraft noise problem have tried to confirm. To overcome these limitations and establish appropriate measures against noise, we made noise map with INM version 7.0, FAA aircraft noise prediction program, and evaluated aircraft noise. To overcome these limitations and establish appropriate measures against noise, we made noise map with INM version 7.0, FAA aircraft noise prediction program, and evaluated aircraft noise. In particular, the FAA's Integrated Noise Model(INM) is widely used by the civilian aviation community for evaluating aircraft noise impacts in the vicinity of airports. We analyzed noise impact by applying several scenarios. As these analysis, we suggest flight route without overlapping with residential area and without affecting flight safety.

  • Depending on the transportation, information and communication technology development, urban such as the superficial spreading and the changing structure of internal space of the organism has various shape and speed of the changes. In particular, the main cause of these changes is the development of the traffic and this transport system is having a close connection with land use. This study presents the results about characteristics and changes of noise on each land use zoning. Therefore the result shows that the measured data could be used to evaluate noise distributions on urban land use and then make up the basis process for producing noise maps of land use zoning.

  • 편집자주 : 일반적으로 공해중에서도 가장 심한 것이 소음과 진동문제로 생각된다. 고무공업에 있어서의 소음과 진동은 지산업에 비해 다소 적다고 한다. 용도지역별로 보면 지산업과 마찬가지고 거주지역과 준공업지역에서 압도적으로 많다고 한다. 한편 최근에는 저주파진동(공기진동)까지도 주의할 필요가 있다고 한다. 본고는 일본 석천도방음공업(주)의 연구논문에거 발췌한 것으로, 특히 고무공장의 공해문제대책에 많은 도움이 되었으면 합니다.

  • Using road traffic noise, noise map for CheongJu city was drawn. Noise level is estimated and many regions of the city are classified noise excess area compared with environment standard value. Counterplan for the noise excess areas is presented in this study. Noise reduction methods are given in many ways, for example soundproofing walls, low noise pavement, low noise arrangement of buildings and low noise windows.
