Aviation Noise Problems - Solutions from Dedicated Research

Kurzfassung

Aviation noise has evolved into one of the environmentally most disturbing factors of airborne transportation. Aviation noise is a particular problem near densely populated areas in Europe, the the Americas and the Far East. To counter the associated adverse effects of the expected growth of aviation over the next decades, problems need to be resolved on time, and well before the technology is critically needed, in order to try to - at least - let not increase community noise impact, better still reduce it. Accordingly, research to help alleviate the expected future problems associated with aviation noise, and to find ways to minimize its adverse effects as much as possible, is intensified worldwide. This paper discusses approaches undertaken to understand the physics of aviation noise and to find technically feasible ways and means to reduce it already at source. Corresponding efforts are illustrated along several selected dedicated projects, related,.
