Review of strategies for mitigation countermeasures of aircraft noise in Japan and current issues

Abstract

In Japan, systematic countermeasures against aircraft noise have already been implemented since the 1970s. It is also in accordance with the later ICAO Balanced Approach. The measures could be divided into three main categories, which are reducing of noise source, Improvement of airport structure and facility, and countermeasures for remedial compensation. The priority strategies were placed on introduction of low-noise aircraft, restrictions on night flights, construction of offshore airports, and remedial compensation such as soundproofing for houses etc. As a result, by the 1990s, compensation measures for severe noise were completed, and nighttime flight restrictions prevented health effects resulting from sleep disturbance. However, since the beginning of the 2000s, residents' acceptance of aircraft noise has changed, and issues have appeared regarding not so loud noise at locations far from airports. In addition, some airports are expanding late-night operations to meet the recent growth in aviation demand. This paper describes the review of strategies of mitigation countermeasures for aircraft noise in Japan and current issues such as the new phase for making coexisting with surrounding residence area in currently, and the need for strategies.
