The main objective of our study is to integrate aerodrome noise data in realtime and to develop analyzing model to enhance interaction between residents and government regulators who are affected closely with aerodrome noise policies. The study will also examine the needs to establish an institution that can consistently monitor and collect aerodrome noise data where it can provide necessary data and information for government regulators to implement noise related policies with great efficiency. In order to achieve our objective, the study came to a conclusion that sharing result of analyzed material such as residents' demand, information on world-wide issues, progression of government policies in real-time is imperative. Moreover, the study further proposes to develop a tool that select and prioritize appropriate analyzing model that will assist regulators when implementing policies on air-noise issue. Based on factors stated above, the report will also explain the need and expected outcome of establishment of CANON (Center of Airport Noise and envirONment Analysis). When analyzing the demands of the residents and government's direction of policies; the study have found that in order to build consensus between residents and government on relevant noise policies provision of objective information to the public via interconnected systemic tool is imperative. At the same time, development of noise analyzing model through monitoring aerodrome noise in realtime is required. The finding have also suggested that establishment of an institution to handle data and information is needed for transparent and objective government policy implementation. To conduct and perform duties in accordance with national air noise rules and regulations, the study has shown that an institution with analysts and staff is required not only to manage information and data but also to consistently conduct research on aerodrome noise abatement effort; which is an on-going global trend. The study has also analyzed currently operating noise monitoring system and examined case studies on realtime data integration system to construct new inter-connective information sharing system. Based on the findings above, the study have proposed plans to integrate data in real-time. However, the study have provided only results of ISP in this report so that further study can be conducted on integration of data in real-time in the future. The discussions is in progress between relevant offices to pursue further study. The function of connectivity (data-link) of Information material was derived from analysis of integration of noise monitoring system and big-data for aircraft noise evaluation system. An integration of automatic noise network analysis will be composed of data link, management of collective data and data record. The Big-data for aircraft noise evaluation system will be composed of management object, analysis and statistical management, and management of results and records. In order to develop aerodrome noise monitoring analysis model, the study has come to a conclusion that consistent collection of data is required and further study must be followed. In regards to selection of analysis model for aerodrome noise monitoring, the study has found optimal analysis model for aerodrome noise monitoring and it has examined its' functions and use of the model. In order to examine feasibility of proposed model, although limited in sources, the study has used Model of Marginal Noise Cost and Analyzed Model of Macroscopic Noise Effect Causes. In the cases of Noise index which requires consistent and comprehensive studies, it will provide brief outline as to how noise index can be constructed. The model simulation has shown that it is surprisingly effective in policy implementation and it was found to be useful as a model for further in-depth study. For a successful realization of an institution the study provide detailed guidelines on plans and objectives as well as functions of the institution. Furthermore, the study elaborates on policy expected outcome in terms of policy compliancy and non-compliancy perspective.
Also, the study have examined the reason for continuos study on this subject through economic feasibility study. On particular note, the participants of the research have actually conducted duties that CANON (Center of Airport Noise and envirONment Analysis) is expected to carry out simultaneously; thereby assisting government regulators. The duties include but not limited to publication of monthly articles, world-wide trend and issues and more throughout the research period. The result of our simulation is in the report and all the progress are listed in the annex of this report. In conclusion, the study reflects and considered current demands and situation of the public and of government regulators' and provides path to resolve current conflict as well as outcomes. Based on the study provided we hope to realize information material sharing system as well as analysis model. Furthermore, in order to implement noise policies, an institution specializing in this area is critical to success.
