摘要：	Nearly every person in the United States is affected by transportation-related noise. It affects the ability of people to carry on conversations, to concentrate at work and school, and to sleep. Urban residents face the most substantial impacts, but as airports are expanded and new ones are built, as ground-based infrastructure is expanded, and with the likely advent of high-speed rail, it is anticipated that impacts will expand well beyond the immediate vicinity of major cities to suburban and rural communities. Over the past three to four decades, much has been accomplished with regard to improving the noise climate in the United States, and there are many new technologies offering the possibility of further improvements in the future. In this paper, a brief historical perspective of past milestones in transportation-related noise control is presented, along with a discussion of the current state of the art. Some of the more promising future technologies and research areas in the field are also examined. For convenience, the three primary modal areas, aircraft, highway, and rail, are discussed separately. Because this is not only an era of shrinking research dollars but also a time in which transportation planning needs to take place on a cross-modal level, the need for sharing of resources among different transportation agencies is also discussed.
