Development of an active noise control system for sleeper seats on large commercial aircraft

将调查可能的途径，使用局部有源噪声控制(ANC)，积极减少卧铺座位乘客感受到的飞机机舱噪音。以前的工作主要集中在耳机和直立座椅头枕上，这代表着与这里考虑的部分封闭的卧铺座椅不同的问题。将解决影响现有ANC系统的效率和稳健性问题。将为宽体飞机上的商务舱卧铺座椅生产一个原型系统。第二个成果是建立一个强大的综合系统设计程序，可用于为未来的设计快速开发ANC系统。

Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here. Efficiency and robustness problems that affect existing ANC systems will be addressed. A prototype system will be produced for a business class sleeper seat in a wide body aircraft. A second outcome is the establishment of a robust integrated system design procedure that can be used to quickly develop ANC systems for future designs.
