大型客机舱内声学设计方案综述(一)

噪声是飞机的固有特性，舱内噪声伴随着飞机从地面开车、起飞到降落的整个旅程，严重影响乘坐舒适性。由于降噪效果的局限性，如何在设计的初始阶段，就将声学设计融入到飞机设计中显得尤为重要，也是需要长期探索和研究的问题，正是基于上述因素提出大型客机舱内声学设计方案。

Overview of the Cabin Acoustic Design for the Large Commercial Aircraft(I)

Acoustic performance is a characteristic of aircraft, relating the amenity of the civil aircraft during the grounding, the take off, the cruise and the landing. Own to the hmitafion of the reducing noise method, it＇s very important for aircraft designer that it need to be intro- duced the acoustic engineering into the aircraft design when the concept design process. It is an issue for studying and researching along time. Therefore, based on the above-mentioned situations, the paper overviewed the main cabin acoustic program of the large commercial aircraft.
