Air transportation has become a common means of transportation in recent years due to economic development and advances in aviation technology. However, while aircraft offer convenience in terms of speed and freedom of movement, they have also caused environmental problems such as noise and air pollution around airports. Therefore, many large airports measure noise levels in order to assess the impact of aircraft noise and take countermeasures. While international standards such as ICAO Annex 16 and ISO 20906 exist for aircraft noise measurement, they do not account for the specific conditions of each airport or the legal frameworks of individual countries. As a result, when comparing measurement practices across airports, differences can be observed in noise identification methods and the metrics used for data analysis. Additionally, priorities vary among airports regarding noise measurement, flight path aggregation analysis, and the disclosure of measurement results. Therefore, we investigated the aircraft noise measurement system at major airports in each country and the legal framework related to aircraft noise mitigation based on publicly available information. Furthermore, based on the results of comparative analysis of the investigation, it will be reported that differences in stance toward the accuracy of measurement and information disclosure.
