Systems and methods for performing noise reduction in a vehicle comprising a\nnoise\nreduction system and a plurality of zones are herein provided. A noise\nreduction criterion\nfor the vehicle is obtained. A first one of the plurality of zones for which\nnoise reduction is\nto be performed ...
Optimising aircraft operations and air traffic management practices are other ways we can reduce CO2 emissions. Discover how Airbus is working towards a world of self-piloting urban air mobility vehicles and cargo drones, and more autonomous… ...
"We're aiming for a one to three decibel reduction per airframe element," said Manoha. "Each step forward is progress." In any case, residents near European airports will have to remain patient. Although some technologies might be retrofitted on existing aircraft, significant relief from air-t...
A noise reduction assembly located at a junction plane between an air intake structure and a fan casing of an aircraft turbojet has improved acoustic properties since the alternation of acoustic and non-acoustic zones is displaced or eliminated. In particular, the inner wall of the air intake ...
In an effort to reduce the level of noise both inside and outside of the aircraft, techniques have been developed that attempt to quiet the environment. The simplest approach uses passive noise reduction methods, including installing acoustic insulation and exhaust modifications, but these only ...
The aim of this article is to provide a broad overview of current and future noise reduction technologies used in aircraft industries. It starts by recalling the regulation framework and the European incentives that have triggered efforts in this domain, as well as the major dedicated EU research...

noise on local residential buildings was to design a plan for proper land use. Up to now, studies on applying different noise reduction strategies for aircraft noise in airports have been numerous. However, systematic investigation of different noise reduction strategies for a jumbo international ...
The statistical method was used mostly during the airport database processing, when the traffic data were collected and analysed to determine aircraft delays connected with the Total Airport Management. Methods of analysis and synthesis were used according to the collected information and traffic data ...
